[PATCH v2 0/3] a few test.py improvements

[David Lechner]

While trying to run the test suite for the first time, I encountered a
few minor issues. Here are a few patches to address them.

---
Changes in v2:
- Dropped patch adding setuptools to test/py/requirements.txt
- New patch to add setuptools to scripts/dtc/pylibfdt/requirements.txt
  instead.
- Changed test.py patch to set ubconfig to None rather than checking for
  its existence in globals().
- Link to v1: https://lore.kernel.org/r/20251121-a-few-test-py-improvements-v1-0-bacb4148fb0d@baylibre.com
