testutil: whitelist WaitGroup.Done
Calling a WaitGroup.Done() in a defer will sometimes trigger the leak detector since the WaitGroup.Wait() will unblock before the defer block completes. If the leak detector runs before the Done() is rescheduled, it will spuriously report the finishing Done() as a leak. This happens enough in CI to be irritating; whitelist it and ignore.release-3.3
