Remove compatibility with old klm
When the open source klm was integrated, it was done so in a way that allowed someone to drop in the older binary blob. Given that we've now had significant production experience with the new klm, there's no point going back. It makes more sense that if a new issue is encountered, we'll just fix whatever happened with the new one. This work should cover removing the wrappers and presumably any other module stubs that existed as a side effect.
