Fix AttributeError for paho-mqtt < 2.0 compatibility (#321)

Browse Source 
When paho-mqtt < 2.0 is installed (e.g. in cached Docker layers),
mqtt.CallbackAPIVersion does not exist, causing an immediate crash on
startup with:

  AttributeError: module 'paho.mqtt.client' has no attribute 'CallbackAPIVersion'

Add try/except fallback so the addon works with both paho-mqtt 1.x and
2.x, eliminating the crash and allowing the addon to start correctly.
