Increase Lulu pressure change cutoffs

There have been dogfooder reports of jerky cursor movement that seem
to be the direct result of Lulu having high speed pressure changes
that cause the gestures library to think a finger is coming/going and
thus supress pointer movment.  This patch increases the values of two
gestures parameters for Lulu that seems to help.

BUG=chromium:523350
TEST=manual testing on a regression test made from feedback reports and
manual testing on a Lulu.
