RFR[9]: JDK-8165566: sun/security/ssl/SocketCreation/SocketCreation.java fails intermittently: Address already in use

[John Jiang]

Hi,
Please review this fix for JDK-8165566 on test 
sun/security/ssl/SocketCreation/SocketCreation.java.
This test takes multiple servers to use one port in sequence, but the 
port may not be released by previous server.
This patch takes every server to be allocated a free port.
