RFR[13] JDK-8219723: javax/net/ssl/compatibility/Compatibility.java failed on some SNI cases

Hi,
Test javax/net/ssl/compatibility/Compatibility.java failed due to the 
associated certificates are expired.
This fix just re-generates the certificates and set much longer validity 
period.

Issue: https://bugs.openjdk.java.net/browse/JDK-8219723

Best regards,
