Switch CI to Nix flakes

We also move tests to Flakes.

This would allow users to submit PRs with a fork of nixpkgs when they
want to test nixpkgs PRs against SNM.

Run NixOS tests
---------------
You can run the testsuite via
To run the test suite, you need to enable `Nix Flakes
<https://nixos.wiki/wiki/Flakes#Installing_flakes>`.
You can then run the testsuite via
::
$ nix-build tests -A external.nixpkgs_20_03
$ nix-build tests -A internal.nixpkgs_unstable
...
$ nix flake check -L
Since Nix doesn't garantee your machine have enough resources to run
all test VMs in parallel, some tests can fail. You would then haev to
run tests manually. For instance:
::
$ nix build .#hydraJobs.x86_64-linux.external-unstable -L
