[PATCH app/xinput] Teach --set-button-map about pointer: prefix.

[Eric Gillespie]

Some highly configurable pointing devices also act as keyboards.

For consistency with other commands, use xi2_find_device_info .

As the build already fails without XInput2, not making conditional on
the HAVE_XI macro.  Suggest removing it, in fact.
