sysutils/bup: Update to 0.33.2

Upstream NEWS less some bugfixes and minor improvements:

Notable changes in 0.33 since 0.32

  Python 3 is now required, in particular 3.7 or newer.

  The version of Python is no longer determined by the value of PYTHON
  during ./configure. It is now determined by the version of
  python-config selected during configuration. The BUP_PYTHON_CONFIG
  environment variable can be set during configuration to select a
  particular executable (e.g. BUP_PYTHON_CONFIG=python3.9-config
  ./configure). See the README for further details.

  The bup executable is now a binary rather than a Python
  script. Practically speaking, this means that the Python version is
  determined by the libpython that the executable is linked against
  (selected via python-config), and it means that bup will show up as
  "bup" in process listings rather than a python invocation.

  The output of bup ls for multiple paths includes each path before
  its contents, more closely matching the system ls.

  The bup ftp ls command should now respect the working directory (set
  by cd), and that directory has been added to the prompt.

  The index-cache is no longer included in the bup midx --dir default.

  Performance may have improved after the relocation of a number of
  operations from Python to C, and a number of improvements to the
  VFS.

Bugs

  Bup should now respect the current umask, directory sgid bit,
  etc. when creating new files (e.g. new packfiles). Previously, it
  would create them via mkstemp, which would cause them to be readable
  only by the current user.

  Bup should now be able to handle repositories containing signed
  commits.

  bup tag has been changed to rely on git update-ref instead of
  writing the (loose) refs directly so that it can handle packed refs
  correctly.

  bup save should be more careful about noting an error and skipping
  paths whose type (link, regular file, ...) has changed since
  indexing.

  There should no longer be a narrow window where save could store
  conflicting symlink targets or conflicting sizes (in the metadata
  record and the packfile symlink blob) for a path if the filesystem
  changed at just the wrong time during a save.

  bup fuse should no longer become unusable after an unfinished read
  of commits associated with tags. The underlying VFS issue may have
  affected other commands too.

  Bup's packfile names should now match git's. Previously bup computed
  the SHA1 from just the sorted object list (cf. git-index-pack(1)),
  but git appears to include the entire pack file in the hash.

  Passing idx files to bup midx along with --dir should now work
  correctly.

  Resource usage (e.g. memory) may have improved, given a number of
  changes intended to make bup release resources more carefully and
  sooner.

Build and install

  The build process should now work on systems where make isn't GNU
  Make (the Makefile automatically redirects to GNUmakefile).
