Subject: [PATCH] libgpiod: update to 2.0

This updates this library to the latest major version.

Since the Python binding build changed in this version,
let's switch to the Py3Package infrastructure.

Also the older v1 kernel interface is not used anymore,
so we can drop this part of the kernel configuration.
