iotests: Accommodate async QMP Exception classes

(But continue to support the old ones for now, too.)

There are very few cases of any user of QEMUMachine or a subclass
thereof relying on a QMP Exception type. If you'd like to check for
yourself, you want to grep for all of the derivatives of QMPError,
excluding 'AQMPError' and its derivatives. That'd be these:

- QMPError
- QMPConnectError
- QMPCapabilitiesError
- QMPTimeoutError
- QMPProtocolError
- QMPResponseError
- QMPBadPortError
