[gnome-settings-daemon/wip/carlosg/remove-device-mapper: 75/84] plugins: Add GDK_BACKEND #define for the GTK+ skeleton

[Carlos Garnacho <carlosg src gnome org>]

commit 562ead5820a89679891655bd77d8c43878e70821
Author: Carlos Garnacho <carlosg gnome org>

    plugins: Add GDK_BACKEND #define for the GTK+ skeleton
    
    Not all plugins that use GDK mandate X11. Leave the allowed GDK
    backend (if any) as an individual plugin decision.
