[PATCH 07/10] iotests/297: return error code from run_linters()
This turns run_linters() into a bit of a hybrid test; returning non-zero on failed execution while also printing diffable information. This is done for the benefit of the avocado simple test runner, which will soon be attempting to execute this test from a different environment. (Note: universal_newlines is added to the pylint invocation for type consistency with the mypy run -- it's not strictly necessary, but it avoids some typing errors caused by our re-use of the 'p' variable.)
