We automatically kill all unpriv user programs on shutdown.

We do not kill processes from system service units that have
KillMode=process, and thus explicitly requested to be exempted from
the "kill all my processes" logic, and are expected to clean up after
themselves on their own. SysV scripts set that for compat reasons. I
cannot fix sysv for your sorry, it works like it works, and does not
clean up properly.
