[libcxx testing] Make three locking tests more reliable
The challenge with measuring time in tests is that slow and/or busy machines can cause tests to fail in unexpected ways. After this change, three tests should be much more robust. The only remaining and tiny race that I can think of is preemption after `--countDown`. That being said, the race isn't fixable because the standard library doesn't provide a way to count threads that are waiting to acquire a lock.
