replace "path:" with "./"

on newer nix versions (> 2.18) the "path:" settings
will lead to evaluation errors when the flake uses
symbolic links.

a typical error message would be:

`error: access to absolute path '/lib' is forbidden in pure evaluation
mode (use '--impure' to override)`

when `/lib` actually is `./lib`.

When "path:" is replaced by just using the flake's path
no evaluation error is shown. As per the man page of `nix flake`
the "path" attribute reffers to the local path of the flake.

This can just be removed (AFAIK) by referencing to the path as a
positional argument.
