'guix copy' does not currently support the 'user@host' style.  Instead
you have to configure your ~/.ssh/config such that 'ssh hostname' works,
then you can use guix copy --to=hostname-or-ip.

I suspect adding support for 'user@host' should not be too difficult,
without having looked at the code ;-)
