Touchbot: Auto detect port for point_picker.py

Point_picker.py still had a hardcoded serial port device left over from
when it was originally written.  It was overlooked until now because
apparently it happened to be the correct device on most Chromebooks, but
proved to be incorrect on Snow.  This updates point_picker.py to use the
automatic serial port scanning technique that everything else uses.

BUG=chromium-os:39358
TEST=Ran on a Snow and it found the correct port and was able to control
the robot with it.
