Fix the last test_ssl failure (test_protocol_sslv2) for CPython 2.7.8 and .9. In python Issue 20207, the SSLv2 protocol was disabled by default, and thus the test was changed to expect a failure (see https://github.com/python/cpython/commit/65f2fdce200b800bd95ac6690e9654afc37897c6).  Match that change.
