[mutter] Work around g-ir-scanner problem with Gdk.Rectangle

[Owen Taylor <otaylor src gnome org>]

    Work around g-ir-scanner problem with Gdk.Rectangle
    
    g-ir-scanner is currently buggy and confuses the Gdk.Rectangle alias
    with MetaRectangle. Since this is moderately hard to fix in
    gobject-introspection and the fix would conflict with in-progress
    changes, work around by doing a 'sed job' on the generated Meta.gir.
