[8u] RFR 8085192: java/rmi/activation/Activatable tests fail intermittently due to "Port already in use"

[Zhengyu Gu]

I would like to backport this patch to 8u for parity with Oracle 8u301.

The original bug: https://bugs.openjdk.java.net/browse/JDK-8085192
The original patch: 
http://hg.openjdk.java.net/jdk9/jdk9/jdk/rev/a80fd00b0cd0

8u webrev: http://cr.openjdk.java.net/~zgu/JDK-8085192-8u/webrev.00/

The jdk9 patch does not apply cleanly.

- Need manual merge @build lines for almost all tests, due to jdk9 tests
   are surrounded by module imports.

- Removed module option from RMDI.java

- java/rmi/activation/Activatable/extLoadedImpl/ext.sh test needs
   to set classpath and enable additional permissions (to match
   other tests) to pass. See patch [1]

Test:
   java/rmi/activation/Activatable all passed.

Thanks,

-Zhengyu
