[gtk/wip/baedert/for-master: 20/39] label: Fold function into only caller

[Timm Bäder <baedert src gnome org>]

    label: Fold function into only caller
    
    This makes it more obvious that gtk_label_setup_mnemonic() depends on
    the root of the widget and it therefore makes sense to call it in
    ::root/::unroot.
