[gnome-shell/benzea/fix-x11-login: 6/7] data: Only unset environment when the service actually ran

    data: Only unset environment when the service actually ran
    
    ExecStopPost= is executed even if ExecCondition= fails. As such, we need
    to add a guard as we would otherwise clear environment variables on X11
    sessions (rendering them utterly useless).
