Add fwupdate-i2c user and group for etphidiap touchpad FW updater.

The fwupdate-i2c user is also placed in i2c group for access to
i2c-dev device files.

BUG=b:79157488
CQ-DEPEND=CL:1532980
TEST=Built OS image with TP FW updater, installed it on Atlas DUT, invoked
chromeos-touch-update.sh.  That successfully flashed the TP FW when it was
out of date, and quietly did nothing when TP FW was up-to-date or newer (no
downgrading by default).
