bitbake: data_smart: Variable references don't contain newlines, spaces or tabs

The code is happily trying to expand variable names containing newlines,
spaces and tabs which are illegal characters in variable names. This
patch stops it doing this. This will change dependency checksums
since some rather weird dependencies were being attempted to be expanded.
