[OE-core] [PATCHv3 1/6] license.bbclass: Write recipeinfo file in license folder

[mariano.lopez at linux.intel.com]

From: Mariano Lopez <mariano.lopez at linux.intel.com>

Currently there is no way to get the recipe version when
creating the rootfs. It is needed because the manifest
file for the image has to contain this important piece
of information.

This change writes a new file in the license folder for
every recipe. This file is called "recipeinfo" and have
the information used to write the manifest file for the
recipes deployed next to the image.
