[gtk/kill-containers: 67/76] shortcutsgroup: Drop container bits

[Matthias Clasen <matthiasc src gnome org>]

    shortcutsgroup: Drop container bits
    
    When GtkBox stops being a container, GtkShortcutsGroup
    will also no longer be a container. So, stop overriding
    container vfuncs, and instead add a buildable implementation
    that does the right thing.
