bitbake: bitbake: Warn upon finding tab indentation in python functions

Mixed spacing in python functions can cause subtle issues and
generally confuses users. We've standardised on 4 space indentation,
adding this warning helps ensure consistency and avoid bugs. It
also makes _prepend and _append operations on python functions slightly
less risky.
