/**
Wrap a derivation such that instantiating it produces a warning.
All attributes apart from `meta`, `name`, and `type` (which are used by
`nix search`) will be wrapped in `lib.warn`.
All attributes will be wrapped with `lib.warn` except from `.meta`, `.name`,
and `.type` which are used by `nix search`, and `.outputName` which avoids
double warnings with `nix-instantiate` and `nix-build`.
