This patch is a melding of upstream's changes and Arch Linux's patch
to logutils/dictconf.py and tests/test_dictconfig.py

https://bitbucket.org/vinay.sajip/logutils/commits/c032f726c36d4f932b5a902fdb048f9f07c40d0d
https://gitlab.archlinux.org/archlinux/packaging/packages/python-logutils/-/raw/main/logutils-python3-13.patch

Neither works for us. Upstream's change depends on logging._lock_acquire
and logging._lock_release, neither of which seem to be available in either
python 3.12 or 3.14.
Arch Linux's change works fine for python 3.14 but breaks with 3.12.
