* Copy test_exceptions.test_unraisable() to
  test_sys.UnraisableHookTest().
* test_exceptions.test_unraisable() uses catch_unraisable_exception();
  simplify the test. test_sys now checks the exact output.
* Use catch_unraisable_exception() in test_coroutines,
  test_exceptions, test_generators.

Avoid the need for try/finally: __exit__ clears unraisable to break
the reference cycle.
