wayland: Don't send wl_data_offer.finish on version 1 offers

QWaylandDataDevice::data_device_drop() called wl_data_offer.finish()
unconditionally when accepting a drop from another client. The finish
request only exists since wl_data_device_manager version 3, so calling
it would trigger a protocol error on compositors supporting v1 or v2
(e.g. Qt Wayland Compositor).
