Skip excluded patterns in detection and snapshots

In ReportDetectedCookies, silently skip cookies that match an
excluded pattern instead of recording them. Filter excluded
patterns in SQL when building version snapshots so they never
appear in the published banner config. Add Excluded field to
UpdateCookiePatternRequest.
