[gtk+/wip/colorchooser-v2: 51/77] color-widget: use a GtkBox for the custom section

[Cosimo Cecchi <cosimoc src gnome org>]

    color-widget: use a GtkBox for the custom section
    
    Since we only allow a single row there, it's better to just use a
    GtkBox, and use :first-child, :last-child and :only-child to style
    swatches in there.
