[LTP] [PATCH] openposix: sem_timedwait: replace sleep with tst_process_state_wait3

LGTM.

I also wonder if other tests with sleep(1) are relevant. e.g.

conformance/interfaces/pthread_rwlock_timedrdlock/6-2.c
conformance/interfaces/pthread_rwlock_timedwrlock/6-2.c

(There are more sleep() uses, but I suppose others aren't relevant.)

Also, some tests (e.g conformance/interfaces/clock_nanosleep/1-3.c updated few
years ago) did not updated sleep() in docs comment.

Kind regards,
Petr
