Silvan Mosberger d064d972f0 lib.filesystem.pathType: Improve error for non-existent paths 
Previously it would fail with

  error: attribute 'nonexistent' missing

         at nixpkgs/lib/filesystem.nix:29:10:

             28|     if dirOf path == path then "directory"
             29|     else (readDir (dirOf path)).${baseNameOf path};
               |          ^
             30|

Silvan Mosberger bb6eab0bdb lib.filesystem.pathType: Fix for filesystem root argument 
Previously this function couldn't handle / being passed, it would throw
an error:

error: attribute '' missing

       at nixpkgs/lib/filesystem.nix:24:20:

           23|   */
           24|   pathType = path: (readDir (dirOf path)).${baseNameOf path};
             |                    ^
           25|

Consequently this also fixes the
lib.filesystem.{pathIsDirectory,pathIsRegularFile} functions.
