Speedup nptl/tst-mutex9 and nptl/tst-mutexpi9.
Each test runs for 6s. do_test_clock is called three times where it
sleeps for two seconds and is then checking if the child process
was killed by SIGALRM. The child process tries to lock a mutex
which times out after 0.5s and is setting up alarm(1) before it blocks
due to pthread_mutex_lock.
This patch removes the sleep(2) and reduces the timeout for the first
pthread_mutex_[timed|clock]lock call.
As the nptl tests run in sequence, this patch saves roughly 6s of
runtime for "make check".
ChangeLog:
* nptl/tst-mutex9.c (do_test_clock): Remove sleep and
reduce timeout.
