This update for virtme fixes the following issues:

Update to 1.23:

* Fix breakage with QEMU 8.2.2
* Change behaviour of --kconfig, that will always override
the .config if present (since there is not reason to use
--kconfig and not update the .config).
* It is now possible to force the legacy cgroup v1 using the
option -a "SYSTEMD_CGROUP_ENABLE_LEGACY_FORCE=1": the vng
init script will mimic systemd behavior and mount cgroup v1,
instead of v2.
