With this I'm able to do a fresh config + meson test with all dependencies
correctly propagated.

1. Fix this eval error:
https://hydra.nixos.org/jobset/nix/master#tabs-errors
The dev package output (actually a separate derivation) needs to skip
this for cross just as the main package output does.
2. Deduplicate libs attrset and list.
3. Move `nix-functional-tests` to `checkInputs`.
With the Meson build system, we no longer need a `check` vs
`install-check` distinction, so it is simpler to just keeep
everything in one place.
Upstream `bzip2` does not provide `pkg-config` files. As a result an
attempt to build `nix` on some distributions like Gentoo failos the
configure as:
$ meson setup ..
...
Executing subproject perl
...
perl| Run-time dependency bzip2 found: NO (tried pkgconfig and cmake)
../src/perl/meson.build:68:12: ERROR: Dependency "bzip2" not found, tried pkgconfig and cmake
The change falls back to `bz2` library for such cases.
