Previously cmake-dev held some files which should be in cmake.
- cmake.m4 should be in installed in cmake so it can be used out of the box
- nativesdk-specific OEToolchainConfig.cmake file used to be in cmake, but the
change of default packaging rules move it into cmake-dev. This recipe is the
exception and it should be moved back.
Add the extra paths to cmake, and clear FILES for cmake-dev to ensure nothing
else slips in.
