Bug 1666275 [wpt PR 25649] - sensors: Only call test_driver.set_permission from the top-level window., a=testonly

Automatic update from web-platform-tests
sensors: Only call test_driver.set_permission from the top-level window.

testdriver.js' documentation says "presently, testdriver.js only works
in the top-level test browsing context (and not therefore in any frame
or window opened from it".

If we do not restrict the set_permission() call here, the call to
initialize_generic_sensor_tests() in
generic-sensor/resources/iframe_sensor_handler.html will time out
waiting for it to complete when running the iframe tests outside the
Chromium CI (i.e. in wpt.fyi or with "wpt run").
