src/rss_converter_twitter.com.xsl: add a label to tweets containing GIFs

The static scraped content only provides a preview of GIF files with the
first frame only, just like in the case of videos.

Set a label when a tweet contains a GIF so that the user can decide to
open the tweet in a full fledged browser to properly see the GIF.
