Update to sshfs-3.7.2

I have added a lot of unpleasant hacks to the code in order to make it
work with NetBSD librefuse. We really should fix it. I will probably
do it later. Release notes from the upstream are as follows:

Release 3.7.2 (2021-06-08)
--------------------------
* Added a secondary check so if a mkdir request fails with EPERM an access \ 
request will be
  tried - returning EEXIST if the access was successful.
    Fixes: https://github.com/libfuse/sshfs/issues/243

Release 3.7.1 (2020-11-09)
--------------------------
* Minor bugfixes.

Release 3.7.0 (2020-01-03)
--------------------------
* New max_conns option enables the use of multiple connections to improve \ 
responsiveness
  during large file transfers. Thanks to Timo Savola for doing most of the \ 
implementation
  work, and thanks to CEA.fr for sponsoring remaining bugfixes and cleanups!

* The `buflimit` workaround is now disabled by default. The corresponding bug in \ 
OpenSSH
  has been fixed in 2007
  (cf. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=365541#37), so this \ 
shouldn't be
  needed anymore. If you depend on this workaround, please let the SSHFS \ 
maintainers know,
  otherwise support for the workaround will be removed completely in a future \ 
version.

Release 3.6.0 (2019-11-03)
--------------------------
* Added "-o direct_io" option.
  This option disables the use of page cache in kernel.
  This is useful for example if the file size is not known before reading it.
  For example if you mount /proc dir from a remote host without the direct_io
  option, the read always will return zero bytes instead of actual data.
* Added --verbose option.
* Fixed a number of compiler warnings.
* Improved performance under OS X.

Release 3.5.2 (2019-04-13)
--------------------------
* Fixed "-o idmap=user" to map both UID and GID on all OSs.
* Fixed improper handling of sequential spaces spaces in "ssh_command" \ 
option

Release 3.5.1 (2018-12-22)
--------------------------
* Documentation updates
* Build system updates
* Added "BindInterface" as valid "-o" option.

Release 3.5.0 (2018-08-28)
--------------------------
* Fixed error code returned by rename(), allowing proper fallback.
* Port to Cygwin.

Release 3.4.0 (2018-06-29)
--------------------------
* Make utimens(NULL) result in timestamp "now" -- no more touched files
  dated 1970-01-01
* New `createmode` workaround.
* Fix `fstat` workaround regression.

Release 3.3.2 (2018-04-29)
--------------------------
* New `renamexdev` workaround.

Release 3.3.1 (2017-10-25)
--------------------------
* Manpage is now installed in correct directory.
* SSHFS now supports (or rather: ignores) some options that it may
  receive as result of being mounted from ``/etc/mtab``. This includes
  things like ``user``, ``netdev``, or ``auto``.

SSHFS 3.3.0 (2017-09-20)
------------------------
* Dropped support for writeback caching (and, as a consequence,
  "unreliable append" operation). As of kernel 4.14, the FUSE module's
  writeback implementation is not compatible with network filesystems
  and there are no imminent plans to change that.
* Add support for mounting from /etc/fstab
* Dropped support for building with autotools.
* Added missing options to man page.

Release 3.2.0 (2017-08-06)
--------------------------
* Re-enabled writeback cache.
* SSHFS now supports O_APPEND.

Release 3.1.0 (2017-08-04)
--------------------------
* Temporarily disabled the writeback cache feature, since there
  have been reports of dataloss when appending to files when
  writeback caching is enabled.

* Fixed a crash due to a race condition when listing
  directory contents.

* For improved backwards compatibility, SSHFS now also silently
  accepts the old ``-o cache_*`` options.

Release 3.0.0 (2017-07-08)
--------------------------
* sshfs now requires libfuse 3.1.0 or newer.
* When supported by the kernel, sshfs now uses writeback caching.
* The `cache` option has been renamed to `dir_cache` for clarity.
* Added unit tests
* --debug now behaves like -o debug_sshfs, i.e. it enables sshfs
  debugging messages rather than libfuse debugging messages.
* Documented limited hardlink support.
* Added support for building with Meson.
* Added support for more SSH options.
* Dropped support for the *nodelay* workaround - the last OpenSSH
  version for which this was useful was released in 2006.
* Dropped support for the *nodelaysrv* workaround. The same effect
  (enabling NODELAY on the server side *and* enabling X11 forwarding)
  can be achieved by explicitly passing `-o ForwardX11`
* Removed support for `-o workaround=all`. Workarounds should always
  enabled explicitly and only when needed. There is no point in always
  enabling a potentially changing set of workarounds.

Release 2.9 (2017-04-17)
------------------------
* Improved support for Cygwin.
* Various small bugfixes.

Release 2.8 (2016-06-22)
------------------------
* Added support for the "fsync" extension.
* Fixed a build problem with bitbake
