BUG/MINOR: systemd: report the correct signal in debug message output

Browse Source 
Commit c54bdd2 ("MINOR: Also accept SIGHUP/SIGTERM in systemd-wrapper")
added support for extra signals but did not adapt the debug message,
which continues to report incorrect signal types. Let's pass the signal
number to the do_restart() and do_shutdown() functions so that the output
matches the signal that was received.
