Don't implement `NixPath` for `Option<&P> where P: NixPath`
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.
