Skip falsing on non-touchscreen device sources
Previously we were analyzing the motion event classification to
determine if the device was an accurate tool (stylus, touchpad, etc)
in order to skip falsing.
Instead, we should perform the inverse, and can make the determination
that if the device source does not support SOURCE_TOUCHSCREEN, then
falsing should not be run as there is minimal risk of accidental touches
Additionally, we should not delay processing of MotionEvents on these
types of input.
