[gtk+] Make the action widgets internal children of GtkNotebook

[Christian Persch <chpe src gnome org>]

commit 5bf30c2885253f7687c4f7e03e5f9fd2c9d82922

    Make the action widgets internal children of GtkNotebook
    
    So they're not included in the result of gtk_container_foreach() which
    preserves it as a convenient way to get the list of all notebook content
    widgets.
    
    Bug #601409.
