script tests: fix relative lib path in utils test

utils.pm uses relative include ".." but the path is relativ to the current folder, so it
does not work when running "perl t/utils.t". Just add another lib of "." fixes that. We could
use FindBin but we don't want to make it unnecessarily complicated.
