  1. 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.
