the release v229 removed the use of the group:

        tmpfiles: drop /run/lock/lockdev

        Hardly any software uses that any more, and better locking mechanisms like
        flock() have been available for many years.

        Also drop the corresponding "lock" group from sysusers.d/basic.conf.in, as
        nothing else is using this.

The upstream documentation doc/UIDS-GIDS.md says that basic.conf.in is "the
precise list of the currently defined groups":

    ## Special `systemd` GIDs

    `systemd` defines no special UIDs beyond what Linux already defines (see
    above). However, it does define some special group/GID assignments, which are
    primarily used for `systemd-udevd`'s device management. The precise list of the
    currently defined groups is found in this `sysusers.d` snippet:
    [basic.conf](https://raw.githubusercontent.com/systemd/systemd/master/sysusers.d/basic.conf.in)

    It's strongly recommended that downstream distributions include these groups in
    their default group databases.

Removing the creation of the group also avoids the need to define a GID
for it when using static ids.
