    Include libXrender as a dependency, link it to libmutter
    
    Mutter uses a function from libXrender (XRenderFindStandardFormat in
    src/x11/iconcache.c), but doesn't link to libXrender. This causes
    link issues on systems using the gold linker, particularly with
    -Wl,--as-needed.
    
    Since mutter is using a function from libXrender, adding 'xrender'
    as a dependency seems appropriate, and fixes the issue.
