[40] 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.
