bitbake: codeparser: Skip non-local functions for module dependencies

If modules do something like "from glob import glob" then we end up
checksumming the glob code. That leads to bugs as the code can change
between different python versions for example, leading to checksum
instability.

We should ignore functions not from the current file as implemented
by this change.
