JDK-8158978: ALPN not working when values are set directly on SSLServerSocket

[Bradford Wetmore]

Simple fix/test.
We missed copying the ALPN values from the SSLServerSocket to the SSLSocket.

The test is essentially SSLSocketAlpnTest.java but setting the 
SSLParameters on SSLServerSocket instead of SSLSocket.
