Previously SKE in TLSProxy only knew about one anonymous ciphersuite so there was never a signature. Extend that to include a ciphersuite that is not anonymous. This also fixes a bug where the existing SKE processing was checking against the wrong anon ciphersuite value. This has a knock on impact on the sslskewith0p test. The bug meant the test was working...but entirely by accident! Reviewed-by: Rich Salz <rsalz@openssl.org> (Merged from https://github.com/openssl/openssl/pull/2157)
