Input: alps - use single touch data when v3 mt data contains only one finger
For v3 protocol devices, use the more accurate single touch data when the
mt data contains only one finger. Note the mt data reporting a finger count
of 1 should never happen, but better safe then sorry.
This brings the v3 bitmap handling in line with what the v4 code does,
allowing to factor out the common bits into a helper function.
