[gimp/gtk3-port: 444/444] app: derive GimpStatusbar from GtkFrame not GtkStatusbar

    app: derive GimpStatusbar from GtkFrame not GtkStatusbar
    
    we were not using a single GtkStatusBar features, it was only in the
    way. Remove broken size allocation logic and simply set a minimum
    height of 3em in CSS. Also ellipsize the label, long labels had funny
    effects since changing the overall GimpDisplayShell packing to pure
    GtkGrid.
