tests fail in 2029

While working on reproducible builds for openSUSE, I found that building the openSUSE python-M2Crypto-0.35.2 package with the fix from MR#235 in the year 2029, tests fail from expired SSL certs.

Background: As part of my work on reproducible builds for openSUSE, I check that software still gives identical build results in the future. The usual offset is +15 years, because that is how long I expect some software will be used in some places. This showed up failing tests in our package build. See https://reproducible-builds.org/ for why this matters.
