Decrease Pit TTC pressure threshold
We were missing some taps on Pit because they weren't quite getting
up the the minimum pressure threshold of 25. They seem to be okay with
15 instead and I was still unable to click by resting my palm in any way
that I couldn't produce one with the value set at 25, so there seems to
be no regression.
BUG=chromium:303245
TEST=Regression test suite still passes and manual testing to make sure
that light taps work, and that I'm not accidentally ttc-ing. The log
in the bug when replayed with the new value of 15 does what we want,
too.
