refactor(server): Use wrapper script to avoid path dependency

Instead of requiring the server component to be made aware of the
location of the Nix builder via environment variables, this commit
introduces a wrapper script for the builder that can simply exist on
the builders $PATH.

This is one step towards a slightly nicer out-of-the-box experience
when using `nix-build -A nixery-bin`.
