Merge bitcoin/bitcoin#28936: Change petertodd seeds to petertodd.net

ecb4683 Change petertodd seeds to petertodd.net (Peter Todd)

Pull request description:

  I changed my DNS seeds to .net from .org to avoid issues with DNS blacklisting, that falsely thinks my domain name is pointing to IP addresses with malware and similar things. Right now there are CNAME records, so the .org addresses still work. But eventually, if needed, I'll remove those CNAME's.

    ACK ecb4683 - tested that usable addresses are being returned.
