    screenshot: Remove GNOME Shell implementation
    
    GNOME Shell has started restricting access for it's Screenshot D-Bus API
    to internal components only [1] for security reasons. In other words,
    this will start failing, so remove it in favor of just using the
    freedesktop portal, which should always work.
