Obelisk.Command.Deploy: use `--use-substitutes`

From `man nix-copy-closure`: --use-substitutes / -s Attempt to download missing paths on the target machine using Nix’s substitute mechanism. Any paths that cannot be substituted on the target are still copied normally from the source. This is useful, for instance, if the connection between the source and target machine is slow, but the connection between the target machine and nixos.org (the default binary cache server) is fast.
