[gtk/gtk-3-24] CI: Enable X11 and Wayland backends for Autotools

[Christoph Reiter <creiter src gnome org>]

commit 98b4428543bbd7440dc8a6023896ab50a87231b5
Author: Simon McVittie <smcv debian org>

    CI: Enable X11 and Wayland backends for Autotools
    
    Enabling one backend (Broadway, in commit 1882ff9b) implicitly disabled
    all the others, which was probably not intentional. Bring the Autotools
    build into line with Meson.
