Title: Set wifi mac address during install.

This works in concert with a script we are adding to the device and injects the device specific mac address into the firmware, stored in the device's /persist partition and linked to from the system partition.

This, obviously, requires no modification to d2-common, and doesn't rely on any boot-time hackery. The firmware is set once and persists.
