udev: do not create /var/volatile/run in init script
Previously in udev init, /var/volatile/run had to be created after
mounting all tmpfs filesystems so that udevd can write to /var/run
(a symbolic link to /var/volatile/run). This is because udev is
started before populate-volatile.sh.
Now that /var/run is a symbolic link to /run (a tmpfs filesystem),
/var/volatile/run doesn't need to be created anymore.
