GCM and CCM test support 

Add code to support GCM an CCM modes in evp_test. On encrypt this
will compare the expected ciphertext and tag. On decrypt it will
compare the expected plaintext: tag comparison is done internally.

Add a simple CCM test case and convert all tests from crypto/modes/gcm128.c
