service: give stop and reload scripts their own timeout

Browse Source 
Both were bounded by killdelay, the delay between the stop signal and
SIGKILL, because service_run_script() had nothing else to reach for.
That conflates two things: how long the daemon may take to die, and
how long its stop script may run.

Give each hook a timeout of its own, defaulting to killdelay when
unset, so the existing behaviour is what you get until you ask for
something else.  parse_script() already falls back that way for the
hooks that had one.
