[9] RFR: JDK-8170245 [TEST_BUG] Cipher tests fail when running with unlimited policy

[Valerie Peng]

Anyone has cycles to review this fix?
Some cipher tests fail when running against unlimited crypto policy due 
to hardcoded checks and values.

Changes are straight-forward. However, given the dependency between the 
tests (as they are ported from SQE tests in the previous co-location 
effort), I mostly just made the minimum changes needed for the test to 
work when unlimited crypto policy is in use.
