tests: AES-CTR encrypt test vectors
Verify AES-CTR encryption implementation against the test vectors in NIST SP 800-38a. This implementations was already tested against AES SIV and EAX mode test vectors, but this adds more explicit testing against published CTR mode test vectors. Signed-off-by: Jouni Malinen <jouni@codeaurora.org>
