JDK 9 RFR of JDK-8156176: Mark GenModuleInfo.java and ModuleTest.java as intermittently failing, demote to tier 2

[Hamlin Li]

tools/jdeps/modules/GenModuleInfo.java
tools/jdeps/modules/ModuleTest.java
(from langtools/test)

These two tests are known to fail intermittently (JDK-8153481), they 
should be marked accordingly with @key intermittent jtreg tag in the 
test file, and should be demoted from tier 1 to tier 2 until mentioned 
issue resolved.

webrev: http://cr.openjdk.java.net/~mli/8156176/webrev.00/

Thank you
