646a570dcb webrtc_sendrecv.py: Make it executable 
Why wasn't it already. Tired of typing 'python webrtc_sendrecv.py'.

368d52dfbd webrtc_sendrecv.py: Fix event loop usage for messages 
Instead of creating a new loop, we should just be fetching the running
loop, then doing a blocking network call inside the callback, schedule
it on the event loop. This is what the C example does too.

e24e69f81c webrtc_sendrecv.py: Fix deprecation warning with Python 3.10 
asyncio.get_event_loop() will not implicitly create a new event loop
in a future version of Python, so we need to do that explicitly.

```
webrtc_sendrecv.py:188: DeprecationWarning: There is no current event loop
  loop = asyncio.get_event_loop()
