[gtk/wip/exalm/solid-csd] theme: Fix decoration background

[Alexander Mikhaylenko <alexm src gnome org>]

commit 13c5a54d2fda8f56b57795d0377d2f3c9fbf5a9d
Author: Alexander Mikhaylenko <alexm gnome org>

    theme: Fix decoration background
    
    'window' is not the only toplevel css name, there are also dialoge etc.
    
    Instead of explicitly only including window, set the black background for
    everything except popups.
    
    Instead of including it for csd, exclude it for ssd, this ensures it
    doesn't override solid-csd style.
