Integrate meta-seconorth-nogplv3/fix_small_image

Commit: seco-ne/yocto/layers/meta-seconorth-nogplv3@a81215cb

image: Fixed small image without GPLv3 software

The small packagegroup was missing from the build. Without the small packagegroup, the image can't be build because were missing core components like busybox. Also the multimedia packagegroup was re-added.
