Merge #14970: [net] add dnsseed.emzy.de to DNS seeds

de7266f [net] add dnsseed.emzy.de to DNS seeds (Stephan Oeste)

Pull request description:

  ACK https://github.com/bitcoin/bitcoin/blob/master/doc/dnsseed-policy.md

  I'm willing to keep it up and running, unless something bad happens.
  I have 15+ years experience running dns servers.

  About my setup:

  - the server may change over time, but the service will be up all the time
  - running [sipa/bitcoin-seeder](https://github.com/sipa/bitcoin-seeder) with default settings (and the non-root port redirect)
