Derivations affected by this patch set `__structuredAttrs = true;` and provide their own `builder`, i.e. it's necessary to `source .attrs.sh`. Rather than adding even more `if`-`source` monstrums, I decided to modify all of those derivations to use `buildCommand` or `runCommand`, without `builder` being set. Then, `$stdenv/setup` is sourced already and as a result it's safe to assume that `NIX_ATTRS_JSON_FILE`/`NIX_ATTRS_SH_FILE` point to a usable location both in a build and a shell session.
