Fix Build.results_url to return the correct results URL.

The base URL for results for a particular build is now:
https://storage.googleapis.com/chromium-layout-test-archives/<builder>/<buildnumber>/layout-test-results

For some reason, Build.results_url returned something different from that before; I don't think that Build.results_url has been used recently, so it likely got out of date.
