Now the derivation outputs are parsed up front, we can avoid a reparse by doing it. Also, this just feels a bit better as the `output*` env vars are more of a `libnixexpr` interface than `libnixstore` interface: ultimately, it's the derivation outputs that decide whether the derivation is fixed-output. Yes, hashed mirrors might go away with #3689, but this bit of code would be moved rather than deleted, so it's worth doing a cleanup anyways I think.
