distgit: Apply Kevin's fix to get the static files to show
    
    Basically, we have two places where we apply the rewrite rule
    allowing to access static files either in pagure-dist-git
    or in the regular pagure.
    We had fixed the first one earlier and this commit fixes the
    second one.
