Cygwin: POSIX timer: handle TIMER_ABSTIME correctly for all realtime clocks
Add CLOCK_REALTIME_COARSE and CLOCK_REALTIME_ALARM to the clocks
allowing an absolute timeout value to be used as such in NtSetTimer.
Fixes: c05df02725c59 ("Cygwin: implement extensible clock interface")
Fixes: 013e2bd9ecf85 ("Cygwin: posix timers: Add support for
CLOCK_REALTIME_ALARM/CLOCK_BOOTTIME_ALARM")
