When collecting a script or unregistering a service, cancel timeouts

Both service and sysv stanzas support a cleanup:script (since v4.10), with an
optional timeout.  These timers must be stopped when collecting a PID for an
svc_t, or when unregistering an svc_t, otherwise the timer callback will be
continuously called, reporting "spurious problem", and cause 100% CPU usage.

+---------------------
+
+Minor bug fix release.
+
+### Changes
+ - Add exit status/signal info when a process dies, by Mattias Berthel
+ - Extend `service kill:SEC` to support up to 300 sec.
+ - Extend `norespawn` debug to cover `service_retry()`
+ - Build *without* libsystemd replacement by default
+
+### Fixes
+ - Fix #449: ALSA plugin fail-to-build-from-source
+ - Fix `sysv` stop command process environment, should be same as start
+ - Fix state machine ordering issue: enter new config generation *after*
+   services disabled in previous generation have been stopped
+
+
