libgpiod's Python bindings no longer worked after the upgrade to 2.0.1. The build system installs an egg, which doesn't work in nixpkgs. To fix this, I adopted the same approach I took in #204884. This patch builds the Python bindings as a separate package, using the normal nixpkgs Python infrastructure. Besides fixing the bindings, this has the added benefit of avoiding the need to build a redundant copy of libgpiod as part of the Python bindings package. Lastly, I cleaned up the libgpiod package a bit, removing an unused dependency on kmod and an unnecessary configure flag. I also added the full list of licenses that apply to the package.

Since linux 4.8 the GPIO sysfs interface is deprecated. User space should use

the character device instead. This library encapsulates the ioctl calls and
