The compat unit declared BindsTo=koha.target and After=koha.target while
its ExecStop ran "systemctl stop koha.target". After= orders this unit's
stop before the target's, so the ExecStop waited on a job that could not
run until the ExecStop itself finished. Every "systemctl stop koha-common"
and every "systemctl restart koha-common" hung for TimeoutStopSec (90s
by default) and left the unit in failed state. An async --no-block stop
does not help either: the queued target stop replaces the start job the
restart transaction needs, and everything ends up stopped.
Drop the dependencies. The unit is now a plain oneshot with
RemainAfterExit that starts koha.target in ExecStart and stops it in
ExecStop, which is all the old "service koha-common" UX requires.
Verified with a replica set of user units: start, stop and restart of
the shim each complete in well under a second, restart gives every
service a new PID, and managing koha.target directly is unaffected.
The one cosmetic consequence is that the shim stays "active (exited)"
if koha.target is stopped behind its back; README.Debian says to look
at koha.target for real status.
Also sets SyslogIdentifier so its journal lines are identifiable.
