Add sun/security tests to libcore-crypto-tests rule.

This allows these tests to be run as part of the MTS test rule and thus
be included in API coverage calculations. In addition, I've moved luni/src/test/java/libcore/sun/security/jca/ProvidersTest.java to
ojluni/src/test/java/security/Provider where it still passes but in that way MTS still builds (which it did not with that test because of the BouncyCastleProvider dependency)

Test: m mts
Test:  atest CtsLibcoreOjTestCases:test.java.security.Provider.ProvidersTest
