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.
