[PATCH] Gitweb: Avoid warnings when a repo does not have a valid HEAD

It is possible that the HEAD reference does not point to an existing branch. When viewing such a repository in gitweb, a message like this one was sent to the error log:

  gitweb.cgi: Use of uninitialized value in string eq at /usr/src/git/gitweb/gitweb.cgi line 5115.
