    test-vars: Always build cryptography from source

    cryptography may bundle openssl in the wheel and that causes symbol
    conflicts if a different openssl is provided by the distribution.
    As such, it's probably safer to re-build cryptography ourselves just
    to be sure that the correct distro libraries are used. We may want to
    revert that once we start building wheel packages for openSUSE and
    distribute them in the OpenStack mirrors since every distribution
    well then get a proper wheel file for its needs. See related review
