Bug description:
  [impact]

  in some situations, restarting journald causes assertion failure.

  [test case]

  intermittently, when restarting journald.  See upstream bug for repro
  details.

  [regression potential]

  this adjusts the journal file destructor, so any regression would
  likely occur when cleaning up journal files and/or
  stopping/restarting.

  [scope]

  this is fixed by commit c377a6f3ad3d9bed4ce7e873e8e9ec6b1650c57d which
  is included in Focal.  This is needed for Eoan and earlier.

  [original description]

  While restarting systemd-jounald, the following error message occurs:

  systemd-journald[28007]: Assertion 'f' failed at ../src/journal
  /journal-file.c:143, function journal_file_close(). Aborting.

  release: Ubuntu 16.04.5 LTS
  systemd version: 229-4ubuntu21.22

  This issue is reported at
  https://github.com/systemd/systemd/issues/12400 and solved at
  https://github.com/systemd/systemd/pull/12679

  Please cherry-pick this fix to the ubuntu16.04 package.
