semaphore: Support cancellation in wait functions of semaphore fallback
...

not properly release the mutex in the fallback implementation.

Don't use POSIX semaphores if a MONOTONIC clock is available
...
POSIX semaphores use CLOCK_REALTIME, but our semaphore_t abstraction
expects CLOCK_MONOTONIC based times. Use the mutex/condvar based
fallback if time_monotonic() actuall returns monotonic times.
