[gnome-initial-setup/wip/port-to-gtk4: 3/23] Drop Cheese dependency

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

commit d118d1f14f9eecca1c2935a06d54e0f4e8e00b27
Author: Georges Basile Stavracas Neto <georges stavracas gmail com>
Date:   Tue Jul 5 11:22:34 2022 -0300

    Drop Cheese dependency
    
    Cheese is not ported to GTK4, and it actively blocks our port.
    
    Remove this dependency for now.
