Remove media_vimeo_update_7200() and media_vimeo_file_default_types_alter()

Coming from #1949520: Remove media_youtube_update_7202() and media_youtube_file_default_types_alter()

Now that #1911970: The audio, image, and video file types should default to a wildcard mimetype selector has been committed which defaults the video file type to include all video/* mimetypes, the problematic code in media_vimeo_update_7200() should be wiped out so that it does nothing. This update hook should have been an indication at a problem in the configurable file types which has now been fixed.

Patch is coming.
