udev-164: Update init script to do an explicit add action 

With udev 152 or greater the default action for 'udevadm trigger' was
modified to be 'change' instead of 'add.

To ensure initial coldplug events at boot are seen be scripts the are
expecting them as 'add' events we invoke udevadm with an explicit
'--action=add'.
