[OE-core] [PATCHv2 3/6] license.bbclass: Added function get_deployed_dependencies

[mariano.lopez at linux.intel.com]

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

This change introduce a new function to get the dependencies
that were deployed into the image. It uses BB_TASKDEPDATA
to get all the dependencies of the current task, so it is
possible to get different packages depending at what
point this function is called.
