This was fixed upstream between 3.6.12 and 3.6.14 with this patch by
Bernhard (it’s a small world!):

    tests: Fix status-request-revoked after 2020-10-24
    
    included certs expire 2020-10-24 so this test fails after that date.
    
    Fixes #967
    
    This patch was done while working on reproducible builds for openSUSE.

The question for us becomes how to ensure long-term reproducibility in
the presence of such bugs.

In this case, I think the only solution would be to change the system
clock when one rebuilds GnuTLS (or to use ‘--without-tests=gnutls’, but
you end up with different derivations, which is not necessarily
desirable).

Thoughts?
