Fix pthread.pthread_barrier_smoke test.

pthread_barrier_smoke test uses WaitUntilThreadSleep() to wait until
BarrierTestHelper threads sleep in pthread_barrier_wait(). But this
is flaky as there a two futex_wait places in pthread_barrier_wait.
This patch modifies this test to avoid using WaitUntilThreadSleep().
