MQTT-IO fails to work with updated DietPI >=9.10

[JanFellner]

MQTT-IO fails to start when using a DietPI >= 9.10

When you try to monitor a GPIO with interrupts it simply crashes.

• DietPi v9.11.2
• Raspberry Pi 4 Model B Rev 1.5
• MQTT-IO 2.6.0

Everything was working up to the point where i updated DietPi

The root cause seems to be related to this one: https://github.com/MichaIng/DietPi/issues/7428
