Read MSC_TIMESTAMP from evdev and pass along

This CL passes along MSC_TIMESTAMP if the device reports it.  We will
use this in the touchpad gesture library for more accurate time deltas,
particularly for lux/hammer.

BUG=b:65041115
TEST=Deploy to device which supports MSC_TIMESTAMP: values are
succesfully passed.  Deploy to device without MSC_TIMESTAMP support: no
problems.
