Report touch down on one-finger entry

The current code mistakenly set the pointer logic based on
the single variable, which is false at the entry to one-finger
mode, but true immediately afterwards. This leads to grail
sometimes failing to emit the proper emulation sequence, resulting
in a missed touch in X.

This patch corrects the logic such that the pointer is based directly
on one-finger mode, thereby solving the problem.
