Subject: [PATCH 2/3] emacsPackages.copilot: Configure nix-installed
 copilot-node-server

By default, the copilot Emacs package searches for "copilot-node-server"
in PATH. If copilot-node-server isn't found, the package downloads and
installs it automatically. All of that isn't compatible with the Nix
way of doing things.

This commit configures the package so the package gets the
copilot-node-server from Nix.
