This test may need to be removed for now. OpenSSL's test vectors ostensibly support differing vectors for encrypt/decrypt, but if you look at the vectors supplied for camellia OFB the encrypt and decrypt sections contain identical data.

For the non-file-based test loaders I can pass made-up data that differs between encrypt and decrypt, but for the file loader test I'd prefer to load the real data. Since the real data has no difference this can't really test it. So for now it may be best to just have the other tests.
