RFR 8073113: sun/security/pkcs11/MessageDigest/TestCloning.java failed due to CloneNotSupportedException: SHA-256

I'd like a review for adding this TestCloning.java to the ProblemList.

This change is not because of a functional problem in Java, it's because 
testing continues to occur on unpatched Solaris 10 machines for this 
Solaris bug.  The test will continue to run on Solaris 11, where the 
problem doesn't exist so we are not missing test coverage. 
Additionally, this is only going to JDK8u because Solaris 10 is not 
supported in JDK9.
