    linux-firmware: add LICENSE_FILES and LICENSE file handling
    
    The firmware blobs have all different licenses from the different
    manufacturers of the binary blobs. This information is contained in the
    upstream 'linux-firmware' repositroy.
    
    This commit extends the package handling so that this information can be
    added as an additional argument during packages generation.
