[bug#70179] [PATCH 0/3] Use system nss-certs in Python.

I would change the comment at the top of core.py so it mentions this is
a Guix-specific version of certifi.py, so it’s clear the package has
been altered. You probably don’t need `_CA_CERTS = None`, since the
try…except clause covers all cases.

Otherwise LGTM.
