[OE-core] [PATCH 4/6] udev: fix invoking pmount failed based on sysvinit

[Hongxu Jia]

The pmount is invoked in the udev's mount.sh script, and it needs the
existence of `/var/lock', `/var/lock' is symlinked to `/run/lock'.

When the system is based on sysvinit, `/run/lock' is created by populate-
volatile.sh, if the udev service starts before populate-volatile.sh starts,
`/var/lock' will be a invalid link.

Create `/run/lock' directory at udev startup to avoid this invalid link problem.
