Include verifyHostname in the test instead of calling the hidden API.
This removes a bit of coverage as verifyHostname itself is not tested
anymore, but it still verifies behavior of the verification and state of
the SSL session on socket creation.
verifyHostname is @hide API so it should not be exercised directly by
CTS.
