dev-libs/xdna-driver: fix compilation for live ebuild

Upstream changed the way firmware files are described (was in info.json, now in WHENCE text file).
Let the ebuild use the script from upstream instead of wget-ting files manually.
Note: eventually this will be pushed to some release, then need to rethink the approach
(e. g. consider putting enumerating firmware files in the ebuild itself).
