[gnome-control-center/wip/gbsneto/list-layout: 15/19] window: make the sidelist and first headerbar horizontally equal

    window: make the sidelist and first headerbar horizontally equal
    
    The first headerbar and the sidelist should stay synchronized,
    and this commit does so by setting the width request of the
    headerbar to the allocated width of the sidelist.
