Add an empyt pytest.ini file for webdriver tests
pytest will look for pytest.ini file to determine the value for rootdir.
With this file added, pytest will always set rootdir to webdriver/tests.
Webdriver tests currently fail on the Android WPT builder[1]. The reason
is that rootdir is set to some subdirectory of webdriver/tests, e.g.
/tmp/wpt/webdriver/tests/classic/navigate_to, and that caused fixtures
inside the support directory can not be found.
