    shell: Don't update the visibility of the lock button
    
    Currently the lock button's visibility is updated on permission
    changes - if the active panel does provide a permission object,
    the button is shown, otherwise hidden.
    As GtkLockButton itself does manage its visibility, it is not
    necessary to handle it in g-c-c. In fact it is harmful, as the
    more sophisticated handling in GtkLockButton is overwritten: for
    instances, GtkLockButton hides itself if an action is allowed and
    the permission can not be released. By overwriting the behavior,
    gnome-control-center ends up showing a non-functional button.
