dbus_utils.py: adjust use of get_event_loop for its deprecation

[antonlacon]

This is my understanding of what the addon needs for Python 3.13: LibreELEC/LibreELEC.tv#9374

asyncio.get_event_loop() raises a RuntimeError if there isn't a loop running when it's called. This handles that error by creating a loop when it doesn't find one.

This is my best guess at the correct thing to do. I'm not familiar with asyncio. However, the addon Works For Me.

I have tested and it works for me too with 3.13.1, makes sense based on https://docs.python.org/3/library/asyncio-eventloop.html

Does it need asyncio.set_event_loop(loop)

• Finish deprecation in asyncio.get_event_loop() python/cpython#93453

Sounds reasonable.
