bitbake: bb.{cooker, data}: only emit a var as python if 'func' is set

This avoids a common issue where PACKAGECONFIG is emitted as a function in
bitbake -e when the 'python' flag exists. It isn't a python function unless
both 'func' and 'python' are set. This aligns with the behavior of
emit_func_python.
