Publish revoked DKIM keys in PKCS #8 PEM format

Publishing revoked keys this way is simpler, requires less effort, is
less error-prone, doesn't require software to reconstruct the original
key, and may improve deniability.

I will no longer publish revoked DKIM keys in DNS because it seems to
break the DNS record and it's redundant.
