sysutils/bup: Update to 0.30.1

(0.30.1 is a bug fix release)

Notable changes in 0.30.1 as compared to 0.30
=============================================

May require attention
---------------------

* Previous versions of bup might have saved filesystem directories
  with incorrect metadata, but the file contents should be fine.  This
  could have happened if bup encountered an error while trying to read
  the metadata for one of the files in a directory, or if bup were
  asked to save two different files with the same name to the same
  destination directory (e.g. via the strip/graft options).  In cases
  where this has happened bup may present either generic or incorrect
  metadata for some of the paths in the affected directory.

* The way `bup index --fake-valid` works has been made to match the
  documentation in the man page so that it can actually be used for
  the stated purpose (of avoiding 'boring' files.)

General
-------

* bup should more accurately recognize git versions.  Previously, for
  example, it would reject relase candidates like "1.5.2-rc3"
  or (apparently) "1.5.2-rc3 (something ...)".

* When `BUP_ASSUME_GIT_VERSION_IS_FINE` is set to true, yes or 1 in
  the environment,  bup will assume the version of git that's
  available in the `PATH` is acceptable, and skip the version check.

Bugs
----

(several)

Build system
------------

* The automated tests have moved from FreeBSD 11.2 to 12.1.

* t/test-fuse should be more portable.  In particular, a compatibility
  issue with Fedora 31 has been fixed, and it should be less affected
  by local timezone variances.

* Some internal build dependencies have been fixed.

Thanks to (at least)
