Rename mtb to mt after library changes

The mtb library supplied by touch_firmware_test has been renamed to
mt after the addition of mta support.  This CL changes the names of
the references to mtb.

BUG=none
TEST=manually ran webplot.py and it didn't complain about being
unable to import libraries anymore.
