Parse customization ID better in Wacom updater

Previously Wacom's firmware updater was using the raw customization_id
from VPD to differentiate devices because this was how we did it in a
hack a long time ago for the first Zerg device.  Unfortunately it turns
out that the customization_id may well change between EVT/DVT/MP which
would cause the fw updater to stop working.  In this CL we take
advantage of the fact that the customization_id is supposed to be of the
form "OEM-BOARD" and we parse out just the board name which should be
consistent, and use that only instead.

BUG=chrome-os-partner:61372
TEST=built and deployed on an Electro -- the update worked smoothly
using only the second half of the customization_id
