JDK 9 RFR of JDK-8149003: Mark more jdk_core tests as intermittently failing

[Amy Lu]

java/net/NetworkInterface/NetworkInterfaceStreamTest.java
java/rmi/Naming/legalRegistryNames/LegalRegistryNames.java
java/rmi/Naming/DefaultRegistryPort.java
java/rmi/transport/closeServerSocket/CloseServerSocket.java

Above tests are known to fail intermittently, this patch is to mark the 
test accordingly with keyword 'intermittent'.

bug: https://bugs.openjdk.java.net/browse/JDK-8149003
webrev: http://cr.openjdk.java.net/~amlu/8149003/webrev.00/

Thanks,
Amy
