gesture: add absolute threshold for start of tap for battery
...
Add absolute threshold on delta_z_inner for tap for battery to guarantee
that we have at least some minimum absolute change in z that has started
the tap for battery.
This change makes it such that if the accel readings are really steady
for a while, then a sudden noisy signal doesn't trigger tap for battery.
BUG=chrome-os-partner:34592
BRANCH=samus
TEST=use tapinfo on to observe tap values and do a double tap of varying
intensities. note that it should be just a little less sensitive to weak
taps.
