Stop all creation of a ssh_host_rsa_key.pub. Use openpgp2ssh to get

the fingerprint from the host pgp public key.  Prevents us from having
to maintain the ssh pub key file, and generally makes things simpler.
Also allows us to go back to having import_key take the key on stdin
(which dkg will like).
