Lennart Poettering 846acb6798 binfmt: also unregister binfmt entries from unit
We unregister binfmt_misc twice during shutdown with this change:

1. A previous commit added support for doing that in the final shutdown
   phase, i.e. when we do the aggressive umount loop. This is the robust
   thing to do, in case the earlier ("clean") shutdown phase didn't work
   for some reason.

2. This commit adds support for doing that when systemd-binfmt.service
   is stopped. This is a good idea so that people can order mounts
   before the service if they want to register binaries from such
   mounts, as in that case we'll undo the registration on shutdown
   again, before unmounting those mounts.

And all that, just because of that weird "F" flag the kernel introduced
that can pin files...

Fixes: #14981
