UPBGE: Fix keyboard sensor second modifier.

Previously only the first sensor was taken into account and the
second modifier always ignored.
This was because the check of status[0] and status[1] only which
correspond to the key and first modifier.

The second modifier (status[2]) is now checked as first modifier
and key.

Fix issue: #965.
