BLEThread.run: Reduce notification wait time from 1s to 1ms

Browse Source 
Now notification wait has 1 second timeout. This might be too long for
Lego Boost. Reduce it to 1 millisecond.

If BLE device does not send out any notification, bluepy-scratch-link
wait for 1 second and during this wait, write or read message from
Scratch is not sent to Boost. This is not an issue for micro:bit since
micro:bit sends out notifications frequently, the notification wait
completes before 1 second timeout.

It was reported that Lego Boost has a few seconds latency between Scratch
motor control command execution to Lego Boost motor move. To try out
smaller timeout, reduce the value.
