[gnome-control-center/wip/gbsneto/list-layout: 21/35] build: create another executable for the new layout

[Georges Basile Stavracas Neto <gbsneto src gnome org>]

commit 2bb6d441a7c028ab196e9cde806ff74b2b9a1de3
Author: Georges Basile Stavracas Neto <georges stavracas gmail com>
Date:   Sat May 28 13:25:13 2016 -0300

    build: create another executable for the new layout
    
    This way, we can test both layouts in parallel and, in
    case something goes wrong, we always have to old layout
    as a fallback.
