[glib] Enable contenttype test on W32, tweak it to pass (mostly)

    Enable contenttype test on W32, tweak it to pass (mostly)
    
    * On W32 use a real directory (SYSTEMROOT) instead of '/etc/'
    * Disable test_symbolic_icon() as it can't be passed (symbolic icons are not
      really supported)
    
    * PowerPoint/Gettext test still fails, presumably because msvcrt qsort() moves
      the entires (both have the same priority)
