Support EV_MSC event types for ChromeOS

A vendor reported the remote chromeos support crashing when EV_MSC
events were emitted by their touch device.  This seems to be due to
evtest reporting those events as hexidecimal values instead of base-10.
According to evtest's source there are only 2 events that it does this
for, so this CL adds in a check for those events in an attempt to parse
them correctly.

BUG=chromium:627506
TEST=manually tested, then verified by the vendor
