Remove compat/sys/_time.h

I've gone through everything that it declared to see where it was used,
and it seems that we probably don't need it anywhere.

Here's what it declared, and why I think we're okay dropping it.

o struct timeval {}
  (Used all over, and we can't really get away with declaring it ourselves;
  we need the same definition the system uses.  If we can't find struct
  timeval, we're pretty much sunk.)

o struct timespec {}
  (Used in event.c, evdns.c, kqueue.c, evport.c.  Of these,
   kqueue.c and event.c include sys/_time.h.  event.c conditions its use on
   _EVENT_HAVE_CLOCK_GETTIME, and kqueue() only works if timespec is defined.)

o TIMEVAL_TO_TIMESPEC
  (Used in kqueue.c, but every place with kqueue has sys/time.h)

o struct timezone {}
  (event2/util.h has a forward declaration; only evutil.c references it and
   doesn't look at its contents.)

o timerclear, timerisset, timercmp, timeradd, timersub
  (Everything now uses the evutil_timer* variants.)

o ITIMER_REAL, ITIMER_VIRTUAL, ITIMER_PROF, struct itemerval
  (These are only used in test/regress.c, which does not include _time.h)

o CLOCK_REALTIME
  (Only used in evdns.c, which does not include _time.h)

o TIMESPEC_TO_TIMEVAL
o DST_*
o timespecclear, timespecisset, timespeccmp, timespecadd, timespecsub
o struct clockinfo {}
o CLOCK_VIRTUAL, CLOCK_PROF
o TIMER_RELTIME, TIMER_ABSTIME
  (unused)
