Some games are checking the hid product string of connected gamepads in
order to decide whether or not to activate rumble.

Wine usually delegates these queries to the backend driver, but they
don't always report the same product strings as on Windows. This will
allow to override backend strings with the actual strings as reported
by native drivers.
