Revert the /usr/lib/.build-id/ change
    
    Revert the /usr/lib/.build-id/ change:
      https://fedoraproject.org/wiki/Changes/ParallelInstallableDebuginfo
      says (without any particularly convincing reasoning):
        The main build-id file should not be in the debuginfo file, but in the
        main package (this was always a problem since the package and debuginfo
        package installed might not match). If we want to make usr/lib/debug/ a
        network resource then we will need to move the symlink to another
        location (maybe /usr/lib/.build-id).
      So do it that way.  Of course it doesn't matter, because exclude gets
      ignored due to implementation details.
