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

[Alexander Mikhaylenko <alexm src gnome org>]

commit a664c4c65061f0b39b70ac6dc94e9112ffdf6333
Author: Alexander Mikhaylenko <alexm gnome org>

    theme: Fix decoration background
    
    'window' is not the only toplevel css name, there are also 'dialog' 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.
