Install only listed firmware files

The current make-install procedure leaves lots of garbage files that
aren't really firmware files in /lib/firmware.

Instead of copy-all-and-prune approach, copy only the listed files and
links in WHENCE by make-install for assuring only the proper firmware
files.
