drunc doesn't work with newer versions of Python

[jcfreeman2]

While we currently use Python 3.10.10, this isn't a problem. However, it would be nice to "future-proof" drunc. E.g., drunc runs into problems when Python 3.11.7 is used. If I try running the minimal_system_quick_test.py in a special test area which uses Python 3.11.7, NFDT_DEV_250113_A9, then I get this error message:

n.b. To recreate this, in the work area described you'll also need to locally pip install integrationtest from the head of its develop branch so it includes Eric's fix from DUNE-DAQ/integrationtest#98 .
