Fixes <http://bugs.gnu.org/27157>.
Having a finite default `max-silent-time' value for scripts such as 'guix
environment' could lead to timeouts when building subtitutes; this was
undesirable.
This change also fixes client behavior to match the documentation, which
is that by default the daemon's settings are honored.
* guix/scripts/archive.scm (%default-options): Remove max-silent-time entry.
* guix/scripts/copy.scm (%default-options): Likewise.
* guix/scripts/environment.scm (%default-options): Likewise.
* guix/scripts/pack.scm (%default-options): Likewise.
* guix/scripts/package.scm (%default-options): Likewise.
* guix/scripts/pull.scm (%default-options): Likewise.
* guix/scripts/system.scm (%default-options): Likewise.

Failing to do that, "%p" would be "0" when using "ProxyCommand"
in ~/.ssh/config.
* guix/scripts/copy.scm (send-to-remote-host): Default to port 22.
(retrieve-from-remote-host): Likewise.
* 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.
