Using --extra-files on a non-NixOS source machine causes crash with newer lockfile

[vancluever]

Steps to reproduce

Source machine:

$ nix run nixpkgs#nix-info -- -m
 - system: `"aarch64-linux"`
 - host os: `Linux 6.2.0-36-generic, Ubuntu, 22.04.3 LTS (Jammy Jellyfish), nobuild`
 - multi-user?: `yes`
 - sandbox: `yes`
 - version: `nix-env (Nix) 2.18.1`
 - channels(root): `"nixpkgs"`
 - nixpkgs: `/nix/var/nix/profiles/per-user/root/channels/nixpkgs`

Set up target machine with the 23.05 installer.

• Clone repo flake to a local directory.
• Run nix flake lock --update-input nixpkgs.
• Do a nixos-anywhere run with --extra-files; e.g.

nix run ~/nixos-anywhere -- --debug --flake ./src/etc/nixos#nixos --extra-files ./src root@TARGET

Expected behaviour

Normal install completed w/files copied.

Actual behaviour

rsync crashes when uploading files. Abridged output:

### Copying extra files ###

Additional notes

I initially found this with the nixpkgs package; I guess something has recently changed that has caused mixing system SSH with Nix rsync to crash. Adding rsync to the suffix list that was added in #66 seems to fix the issue.
