libinput-openbsd: fix mouse button ordering

Hi,

libinput has the mouse buttons in order: left, right, middle. So fix
the mappings. While here replace the comment before that code that
doesn't make sense anymore.

I've done this as a patch but if you prefer to commit it upstreams and
do a new release, it also works for me.
