Fix a race condition during the rosalloc verification.

Since an exiting thread could revoke its thread-local runs without
holding the mutator lock, when rosalloc verification is running at a
pause, the thread could concurrently modify runs and cause a race
condition/verification check failure.

Now an exiting thread acquires the mutator lock when it revokes its
thread-local runs, which should avoid the race condition.
