refactor(nixery): Adapt Nix build instructions for readTree

Browse source 
This does not fully change the build structure of Nixery to be
depot-compatible yet, but should allow most targets to be built in
depot CI.

This contains some hacks to work around surface incompatibilities
which we'll clear away later.
