[Vincent Untz <vuntz src gnome org>]

    panel: Do not link the custom CSS for PanelMenuBar to one screen only
    
    Instead of calling gtk_style_context_add_provider_for_screen() in the
    class init method (where we don't have a widget), call
    gtk_style_context_add_provider in object init method.
