    collection-toolbar: Prevent Gtk+ from creating app-menu
    
    AppMenus are going away in GNOME 3.32. So far Boxes was relying on
    Gtk+ to discover the "gtk/menus.ui" resource and create an appmenu
    from it.
    
    The deprecation strategy will add existing app-menus automatically
    in the headerbar, in order to avoid introducing accessibility
    regressions.
    
    This way, we should prevent Boxes' current menu from being mistakenly
    picked up by GtkApplication as a legacy appmenu. We can easily
    achieve this by renaming the menu resource away from "gtk/menus.ui".
    
    See the "Automatic resources" section in the GtkApplication
    documentation for details of this behavior.
    https://developer.gnome.org/gtk3/stable/GtkApplication.html
    
    This is a complementary effort of the AppMenu retirement initiative.

    Fixes #223
