python3: add pending patch fixing support for new LibreSSL version

Add pending patch fixing support for new LibreSSL version.

New LibreSSL version adds support for SHA3 algo but doesn't add support
for SHAKE ones. There is currently a logic error in the Python
test_hashlib that always expect both SHA3 and SHAKE algo to be present.

This logic error cause the Host Python3 to fail testing.

This patch fix the logic error and restore correct compilation of the
host package.
