[gnome-games/wip/exalm/gtk4: 58/62] ui: Use 'icon-name' property of GtkButton

[Alexander Mikhaylenko <alexm src gnome org>]

commit d7c8be4796ab81d6256afa136b2edb187761979f
Author: Alexander Mikhaylenko <exalm7659 gmail com>
Date:   Sun Jul 29 14:59:48 2018 +0500

    ui: Use 'icon-name' property of GtkButton
    
    This sets 'image-button' style class implicitly and also allows to remove
    GtkImage children.
