    data: Flag in desktop file that gnome-shell can be started using systemd
    
    As gnome-shell is a required component for GNOME sessions, gnome-session
    will currently always try to autostart it. However as we are moving towards
    using systemd's user instance for session startup, gnome-session should only
    be responsible for launching the shell when either not running under systemd
    or when we were built without systemd support.
    
    gnome-session can detect the former but not the latter, so communicate this
    via the newly added X-GNOME-HiddenUnderSystemd key in the .desktop file.
