Disable static server key ECDH cipher suites in SSLSocket.

These cipher suites use a static key for ECDH on the server side.
When client certificates are used, a static key is also used on the
client side, leading to the same premaster secret for all connections
between a particular client and server. Also, these cipher suites do
not provide forward secrecy.

Scans show that removing these cipher suites from the default list
does not affect connectivity to servers and is thus safe.
