[tsan] Remove long sleeps from fork tests

On one of our testing machines, we're running the tests under heavy load, and especially in the fork-based TSan tests, we're seeing timeouts when a test uses sleep(10), assuming that calling fork() on another thread will finish sooner than that. This patch removes a timeout and makes another one longer.
