    windowManager: Ignore error without systemd
    
    On systems/setups not using systemd, a failure to start gsd-xsettings
    with NOT_SUPPORTED does not denote a failure to start Xwayland, just
    that we're not using systemd.
    
    In that case, we should just ignore the error, otherwise it will prevent
    Xwayland to start on such systems/setups without systemd.
    
    Thanks to Rose Kunkel (@rosekunkel) for spotting the issue/suggesting
    the fix.
