The bidirectional test attempts to change the cipher to TLS_CIPHER_AES_GCM_128. The test fixture setup will have already set the cipher to be tested, and if it was different than the one set by the bidir test setsockopt() will fail on account of having different ciphers for rx and tx, causing the test to fail.

Forcing the use of GCM when testing ChaCha doesn't make sense anyway, so just use the cipher configured by the test fixture setup.
