ensure sleep_at_least is guaranteed to sleep for the requested duration
Microsoft runs tests in a Hyper-V VM. The test external/wpt/resource-timing/resource-timing-level1.sub.html leverages wptserve's SyntheticResponse.py to request that each step of a response is delayed by 250ms. In our environment, even with the extra 15ms "padding" in sleep.py, we're seeing the timer return 5ms early which in turn causes the test to fail. This change updates the sleep_at_least function to, in a loop, explicitly check that it slept long enough and, if not, sleep again for a short interval.
