Fix flaky futex test.
The test is long running (175128 ms or so) which causes timeouts. The test simply makes sure that private futexes can acquire locks concurrently. Dropping current threads and increasing the number of locks each thread tests the same concurrency concerns but drops execution time to ~1411 ms. PiperOrigin-RevId: 264476144
