Introduce new abstraction, `stdenv/booter.nix` for composing bootstraping stages, and use it everywhere for consistency. See that file for more doc. Stdenvs besides Linux and Darwin are completely refactored to utilize this. Those two, due to their size and complexity, are minimally edited for easier reviewing. No hashes should be changed.
