Drop compile-fixes and upstream-reverts patches
    
    We very very rarely use these.  The last time compile-fixes.patch was
    used was over 3 years ago.  The upstream-reverts.patch has literally
    never been used since Fedora switched to git.  We tend to apply the
    reverts as stand-alone patches anyway, and compile fixes are generally
    better as stand-alone patches that get sent upstream ASAP.
