[pkg-gnupg-maint] Bug#1008573: Workaround for Nitrokey Start

[Giovanni Mascellani]

Hi,

I have a Nitrokey Start that has the same problem, but the suggested 
workaround was not enough for me. After a few attempts, I discovered 
that I need this in my ssh_config file:

KexAlgorithms -sntrup761x25519-sha512 at openssh.com
HostKeyAlgorithms -ecdsa-sha2-nistp256

Notice that after this change connections to hosts that previously used 
a ecdsa-sha2-nistp256 host key will fail key verification and trigger 
the usual scary message about a MITM attack.

Thanks, Giovanni.
