input: Remove --disable-xkbcommon

It looks like there are some code paths where this has been forgotten, so
it likely doesn't work as is.  It's probable that nobody has actually
used this in a very long time, so it's not worth the maintenance burden
of keeping xkbcommon vs raw keyboard code anymore.
