[PATCH 1/1] tools: patman: fix `pip install` with Python 3.12

[Brandon Maier]

Installing patman with `cd ./tools/patman && pip install -e .` fails
with the error below.

As described in the error output, the license line is not allowed to be
only defined in the setup.py.

> $ cd ./tools/patman && pip install -e .
