[Buildroot] [PATCH 1/1] v4l2loopback: new package

[Alexandre Esse]

This package provides a kernel module and utilities in order to use v4l2loopback virtual devices.
This module allows you to create "virtual video devices" normal (v4l2) applications will read these devices as if they were ordinary video devices, but the video will not be read from e.g. a capture card but instead it is generated by another application.
