GMenuModel: remove a type safety bug

Browse Source 
There was a /* XXX */ in the code here to do proper typechecking of the
GVariant in the menu model when using g_menu_model_get_item_attribute().
We have g_variant_check_format_string() now, so use it.

* This function is a mix of g_menu_model_get_item_attribute_value() and
* g_variant_get(), followed by a g_variant_unref(). As such,
* @format_string must make a complete copy of the data (since the
* #GVariant may go away after the call to g_variant_unref()). In
