I don't see why "unknown" is better, it could under certain conditions
be "known", but not trusted.

That already exists:

  crypto/x509/x509_txt.c:

    case X509_V_ERR_DEPTH_ZERO_SELF_SIGNED_CERT:
        return "self signed certificate";
    case X509_V_ERR_SELF_SIGNED_CERT_IN_CHAIN:
        return "self signed certificate in certificate chain";
