feat(nix/addCoverables.nix): allow to configure `uncoverables` paths

Not sure that's the best design/naming/documentation, I just went to the easiest way to enable me to remove `tests/` instead of `test/`.
Let me know if something is amiss, otherwise feel free to modify, merge or discard.

Usage example:
```nix
coverage = pkgs.dekking.makeCoverageReport {
  name = "coverage";
  packages = [
    "GameOfLife"
  ];
  uncoverables = [
    "apps/"
    "tests/"
  ];
};
```
