pythongh-109974: Fix lock_tests: adjust timeouts
c460bfe 
* test_set_and_clear(): increase event wait()
  timeout. Remove sleep after Bunch.wait_for_started().
* BarrierTests.test_repr(): remove sleep after wait_for_started().
  Use way longer timeout for Barrier.wait() timeout.
* test_thread_leak() no longer needs to count
  len(threading.enumerate()): Bunch use
  threading_helper.wait_threads_exit() internally which does it in
  wait_for_finished().
