reporter: Remove default logging to stderr

Logging to stderr causes a lot of unnecessary output when system capture
is disabled, and isn't really necessary with the improved logging
capabilities, so remove it.

Users can still manually enable it with this in their conftest.py:

    def pytest_configure(config):
        logging.basicConfig(
            level=logging.INFO,
            format='%(levelname)7s: %(message)s',
            stream=sys.stderr,
        )
