RFR[14] 8236098:AlgorithmConstraints:permits method not throwing IAEx when primitives are empty

[Anthony Scarpino]

Hi,

I need a code review for a JCK issue where the AlgorithmConstraints spec 
says that permits() with a null or empty primitives throws an 
IllegalArgumentsException.  The code currently allows no primitive and 
continues with the check.  Additionally, there was a needed change to 
JSSE SeverHello that was sending a null primitives.
