Subject: [PATCH] Adapt the flake to nixpkgs' deprecation of the stdenv
 platform predicates

nixpkgs now warns on every access to the `stdenv.is*` shorthands, which hide
the build/host/target distinction
(https://github.com/NixOS/nixpkgs/pull/518407). The nixpkgs pinned here
predates that change, but a future update will surface the warnings.
