[tor-commits] [tor/master] Do not publish the "git-XXX" tag in server descriptors

commit 31eb73f88e858d4dedceb4a748cab5c068896036
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>

    Do not publish the "git-XXX" tag in server descriptors
    
    Instead, allow packagers to put a 'TOR_BUILD_TAG' field in the
    server descriptor to indicate a platform-specific value, if they
    need to.  (According to weasel, this was his use for the git- tag
    previously.)
    
    This is part of 2988
