libgpiod: add new recipe

libgpiod - C library and tools for interacting with the linux GPIO
character device

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 data structures behind a
straightforward API.
