Most Nix functions that accept `NixPath` arguments can't do anything useful with `None`. The exceptions (`mount` and `quotactl_sync`) already take explicitly optional arguments. Also, this changes the behavior of `mount` with `None` arguments. Previously, it would call mount(2) with empty strings for those arguments. Now, it will use null pointers.
