[redbulltv] Remove RedBullTVRrnContentIE extractor

The test cases either are dead links or redirect to a URL that
RedBullTVIE handles. AFAIK, the only usage of rrn in URLs is now for
indicating playlists (rrn:content:collections:...), whose current video
is already handled by RedBullTVIE. Playlist support is not currently
implemented for this domain, and RedBullTVRrnContentIE is never used
with current redbulltv URLs.
