doc: make gendoc.py module import policy aware
Without this, running gendoc.py during an install without C modules
available (via `make local`) will result in an import failure because
the default module load policy insists on C modules.
We also remove the sys.path adjustment because it is no longer needed
since our magic importer handles things.
