Input: fix typo in MT documentation

Section "Event Computation" had this:
    ...
    ABS_MT_TOOL_X := C_X
    ABS_MT_TOOL_X := C_Y

Replace the second ABS_MT_TOOL_X with ABS_MT_TOOL_Y.

 Unfortunately, there is not enough information to specify both the touching
 ellipse and the tool ellipse, so one has to resort to approximations.  One
