Prefer coarse timestamps when using X sync
They are good enough for this purpose, and are cheaper to get.
* src/timefns.c (monotonic_coarse_timespec): New function.
* src/xterm.c [HAVE_XSYNC && !USE_GTK && HAVE_CLOCK_GETTIME]:
(x_sync_current_monotonic_time): Use it.
(CLOCK_MONOTONIC): Remove; no longer uneeded here.
