[OpenAFS] https://lists.openafs.org Web Cert Expired

[Matt Vander Werf]

It looks like the https://lists.openafs.org/mailman/listinfo web
certificate has expired as of earlier this morning. The cert error shows up
in the iframe when clicking on the lists links on openafs.org too.

https://openafs.org by itself seems to be working fine.

Just an FYI to the necessary people to get it fixed.

Thanks.
