Test that generate_test_code.py is still compatible with Python 2
When Mbed TLS 2.16 was released, the requirement was Python 2, not
Python 3. Since then, upstream Python 2 support has stopped, but it is
still maintained in some long-term-support distributions. For the sake
of users who build the unit tests in such environments, test that
generate_test_code.py remains compatible with Python 2.
