Add a test with flake.nix in a submodule

I noticed a regression in the lazy-trees branch, which I'm trying to
capture with this test. While the tests succeeds in master, the
lazy-trees branch gives the following error message:

    error: access to path
    '/build/nix-test/tests/flakes/flake-in-submodule/rootRepo/submodule/flake.nix'
    is forbidden because it is not under Git control; maybe you should
    'git add' it to the repository
    '/build/nix-test/tests/flakes/flake-in-submodule/rootRepo'?
