Normalize asyncio.TimeoutError to builtin in task input timeout (py3.10)

asyncio.wait_for raises asyncio.TimeoutError, a distinct type from the builtin
before Python 3.11, so an elicitation-callback timeout leaked an uncaught type
on 3.10. Convert it to the builtin TimeoutError the rest of the drive raises.
