input.tablet capabilities assignment is wrong, we want to assign it based ont ABS_X, ABS_Y and BTN_TOUCH.
The previous check was hiding behind (ABS_X && !ABS_Y) which (as the comment
suggests) is iffy at best.
Move the check for the BTN_TOUCH bitmask up to the rest of the input.mouse
checking and assign input.tablet accordingly.
Fixed with another commit AFAICS.
btw. for the next time I'd appreciate it if there was a reference to the commit that fixed the issue.
