Use an empty pylintrc for tests using project's pylintrc implicitely

We don't want to use the project's  pylintrc during tests, because
it means that a change in our config could break tests.
But we want to see if the changes to the default break tests.

Create a private '_Run' class in pylint.testutil._run
