bitbake: cooker: Don't expand python functions in variable dumps

We don't want to expand python functions since they aren't expanded
at execution time (e.g. anonymous python). They can also have side
effects.

This function is primarily used by toaster for variable dumps for later
display. The lack of expansion of python functions won't matter in this case
and actively helps some variable handling (e.g. SRCPV).
