Allow pg_ctl kill to send SIGKILL.

Browse Source 
Previously that was disallowed out of an abundance of
caution. Providing KILL support however is helpful to make the
013_crash_restart.pl test portable, and there's no actual issue with
allowing it.  SIGABRT, which has similar consequences except it also
dumps core, was already allowed.
