examples/bluetooth/ble_advertising.py: Fix decoding UUIDs.

Browse Source 
The UUID32 case was incorrect: first, the "<d" should have been "<I", and
second, the UUID constructor treats integer arguments as UUID16.  So this
UUID32 case needs to pass in the actual data bytes.

And then it's simpler to just make all cases pass in the data bytes.
