All tests fail on NixOS unstable

[yvan-sraka]

Hello,

I have some issues recently while running sudo nixos-rebuild switch --upgrade, and after a quick investigation it seems that is because of the cargo test command of nix-du package failed ... here a build log:

running 13 tests

test filter_size_root_not_kept ... FAILED

I hope this could help to investigate this issue.

I think it could be linked to #3

NixOS/nixpkgs#86231 should have fixed this.
