[PATCH] guix: copy: Use userauth-public-key/auto! for ssh authentification.

[Mathieu Othacehe]

* guix/scripts/copy.scm (open-ssh-session): Replace userauth-agent! by
  userauth-public-key/auto!. This way, if ssh-agent is not run,
  default ssh key (~/.ssh/id_rsa) will be used as a fallback.
---
Hi,

I was surprised to see guix copy unable to authenticate to my servers whereas
guix offload is working. It's because guix offload uses ~/.ssh/id_rsa as a
fallback and guix copy doesn't.

With this patch we can keep using ssh-agent in priority
but fallback to default ssh keys if ssh-agent is not started.

Thanks,

Mathieu
