>> The test sun/security/pkcs11/Provider/RequiredMechCheck.java extends sun/security/pkcs11/PKCS11Test.java, which sets up a PKCS11Provider configured with NSS config files located in the source tree directory (sun/security/pkcs11/nss) for the dependent tests to run properly. This test currently fails if that **pkcs11/nss** directory is made read-only because these config files are updated during the test execution. Files located in the source tree should not be modified when running tests. 
>> This PR updates the PKCS11Test to copy the NSS config files to the Jtreg scratch directory and configures the provider to use those files instead.
