0.920 (Released 2021-12-15) is not entirely happy with the
way that I was defining _FutureT:
qemu/aqmp/protocol.py:601: error: Item "object" of the upper bound
"Optional[Future[Any]]" of type variable "_FutureT" has no attribute
"done"
Update it with something a little mechanically simpler that works better
across a wider array of mypy versions.
