Improve logging of forking services having started and stopped

Since a forking service, e.g. a sysv init script, will exit very early
we cannot log the same as for regular services "Starting foo[123]", so
instead we log "Started bar[321]" when we get the pidfile update and
the same when stopping a forking service, log "Stopped bar[321]" when
we collect the PID.
