Update the default enabled cipher suites preference

At present, the SunJSSE provider prefers the better performance of key exchange and digital signature algorithm, in the order of ECDHE-ECDSA, ECDHE-RSA, RSA, ECDH-ECDSA, ECDH-RSA, DHE-RSA, DHE-DSS.

Forward secrecy should be preferable first. If the DHE ephemeral key limitation get resolved, the order should be changed to ECDHE-ECDSA, ECDHE-RSA, DHE-RSA, DHE-DSS, ECDH-ECDSA, ECDH-RSA, RSA.
