Subject: [PATCH] common/xbps-src/shutils/update_check: use info/refs for
 checking common git forges

this endpoint is intended for git usage and while it is "binary", it is text and
has all the tags, which is what we care about

these pages are also much smaller than the web or even an atom feed, so
this should be more efficient
