nixos/tests/openldap: make openldap test auto-callable

The NixOS manual documents that you can invoke every tests using

    nix-build path/to/nixos/tests/test.nix

which was not the case for openldap since it is not autocallable, but
requires pkgs and system as arguments. Usually, make-test-pythons.nix
takes care of this if it is imported at the top-level, but since
openldap.nix contains multiple tests, this was not the case.

This is however easily fixed by:

* Adding default values for the pkgs and system arguments based on the
  definition in make-test-python.nix
* Passing pkgs and system explicitly to make-test-python.nix to ensure
  the pkgs and system values passed from all-tests.nix are used.
