Remove CBC-mode ECDSA ciphers in TLS (removed)

Remove ECDHE_ECDSA_WITH_AES_128_CBC_SHA and ECDHE_ECDSA_WITH_AES_256_CBC_SHA TLS cipher suites. TLS's CBC-mode construction is flawed, making it fragile and very difficult to implement securely. Although CBC-mode ciphers are still widely used with RSA, they are virtually nonexistent with ECDSA.
