rust-core: updated copyright notice
The intention here is to put an email address that actually
works (I did have full personal copyrights with my
former affiliation).
It is also an opportunity to acknowledge that I've not been
the only one to work on this file.

tests: fix failing doctest in match.py by adding dummy auditor
It was failing with "OSError: [Errno 13] Permission denied:
'/root/sub'". It has been failing since
8b1a9ba375e5 (match: make sure
`root` argument is always an absolute path (API), 2019-12-13). I don't
know why I didn't notice it before sending that patch.
