This is not the right way to do this -- we want a checked in vector with teh right bytes, not a mutation of an existing vector.

Makes sense. Added x509/ocsp/resp-unsuccessful-response-bytes.der (resp-sha256.der with the status set to tryLater), documented it in test-vectors.rst, and the test now just loads it.
