    Fix the cmp implementation for variant values
    
    This was causing g_param_value_defaults to return 1
    for GVariant values even when the value is clearly
    different from the default.
    
    This was showing up as gtk-builder-tool stripping
    non-default values for GtkActionable::action-target
    from ui files.
