When checking the current DNSSEC state against the policy, consider
offline keys. If we didn't found an active key, check if the key is
offline by checking the public key list. If there is a match in the
public key list (the key data is retrieved from the .key and the
.state files), treat the key as offline and don't create a successor
key for it.
