failing sanity check for openssl for older Python installations on top of EESSI 2023.04 compat layer (due to OpenSSL 3.0.x)

[boegel]

The installation of both Python/3.9.5-GCCcore-10.3.0 and Python/3.9.6-GCCcore-11.2.0 on top of the EESSI 2023.04 compat layer fails (with OpenSSL in filter-deps in the EasyBuild configuration, cfr. #256) in the sanity check with:

== 2023-06-06 20:22:18,752 build_log.py:171 ERROR EasyBuild crashed with an error (at easybuild/tools/build_log.py:111 in caller_info): cmd "python -c 'from cryptography.hazmat.bindings.openssl import binding'" exited with exit code 1 and output:
Traceback (most recent call last):

The culprit here most likely is that the version of the cryptography extension included in these Python easyconfigs is too old, since cryptography only seems to support OpenSSL 3.0.x starting with v35.0, cfr. https://cryptography.io/en/latest/changelog/#v35-0-0 .

(note that the version of the Rust build dependency for these Python installations had to be bumped to get to this point, cfr. #257)

Problem fixed in new EESSI pilot version 2023.06 by sticking to OpenSSL 1.1.1 for now in compat layer, cfr. EESSI/compatibility-layer#188
