python3-gpiod: new package

Add a recipe for libgpiod v2 python bindings. This is a release
candidate but once the proper v2.0 is released, it will be made public
on pypi and the recipe modified accordingly.

As libgpiod python bindings now use setuptools and not make, we can
separate the recipe from the rest of the library.
