xfs_scrub: fixes for systemd services [v28.3 4/6]

This series fixes deficiencies in the systemd services that were created
to manage background scans.  First, improve the debian packaging so that
services get installed at package install time.  Next, fix copyright and
spdx header omissions.

Finally, fix bugs in the mailer scripts so that scrub failures are
reported effectively.  Finally, fix xfs_scrub_all to deal with systemd
restarts causing it to think that a scrub has finished before the
service actually finishes.
