release.nix: add tarballs to release critical

This catches any build failures that otherwise users might encounter.

For example libseccomp package doesn't build on darwin.

-# Filing a Nix issue
-
-*WAIT* Are you sure you're filing your issue in the right repository?
-
-We appreciate you taking the time to tell us about issues you encounter, but routing the issue to the right place will get you help sooner and save everyone time.
-
-This is the Nix repository, and issues here should be about Nix the build and package management *_tool_*.
-
-If you have a problem with a specific package on NixOS or when using Nix, you probably want to file an issue with _nixpkgs_, whose issue tracker is over at https://github.com/NixOS/nixpkgs/issues.
-
-Examples of _Nix_ issues:
-
-- Nix segfaults when I run `nix-build -A blahblah`
-- The Nix language needs a new builtin: `builtins.foobar`
-- Regression in the behavior of `nix-env` in Nix 2.0
-
-Examples of _nixpkgs_ issues:
-
-- glibc is b0rked on aarch64
-- chromium in NixOS doesn't support U2F but google-chrome does!
-- The OpenJDK package on macOS is missing a key component
-
-Chances are if you're a newcomer to the Nix world, you'll probably want the [nixpkgs tracker](https://github.com/NixOS/nixpkgs/issues). It also gets a lot more eyeball traffic so you'll probably get a response a lot more quickly.

+The Nix Emacs mode supports syntax highlighting, somewhat sensible

+To enable Nix mode in Emacs, add something like this to your ~/.emacs
+file:

+
+This automatically causes Nix mode to be activated for all files with
