Fix a validation bug when owner != signer.
...
Since owner and signer are both domain names and share the same
buffer in memory (daemon->namebuff), we need to go through a little
hoop to make sure one doesn't step on the other's toes. We don't
really need to extract the signer name until we have finished
calculating the hash of the RRset, so we postpone its extraction.
