lmp/build: add support for collecting duplicated sources

On multiconfig machines the sources and the license can be duplicated.
We have two places with the source-code and licenses on the ti bsp [1].
If it was the case we will deploy only one package, we will search for
the first package license path and use that.

We can also escape and jump this source-code collecting step when we not have any IMAGE_MANIFESTS (i.e no image produced).
