JDK 9 RFR of JDK-8137232: Mark 3 more core-libs tests as intermittently failing

[Amy Lu]

Below tests are known to fail intermittently:

java/rmi/activation/rmidViaInheritedChannel/InheritedChannelNotServerSocket.java
java/net/NetworkInterface/NetworkInterfaceStreamTest.java
javax/rmi/PortableRemoteObject/ConcurrentHashMapTest.java

This patch is to mark them accordingly with keyword 'intermittent'.

bug: https://bugs.openjdk.java.net/browse/JDK-8137232
webrev: http://cr.openjdk.java.net/~amlu/8137232/webrev.00/

Thanks,
Amy
