File: entries in the WHENCE file overwrite existing files in the target
directory, however, Link: entries are skipped if the file exists in the
target directory. This can cause issues if the Link: entry is updated, but
the target directory contains an old symlink. Do not skip writing Link:
entries if the file exists, always create the symlink. This matches the
behavior of File: entries and ensures symlinks will contain values from
the WHENCE file.

Rather than require symlinks to be created in the filesystem and have
duplicate Link: entries in the WHENCE file, make copy-firmware.sh create
the symlinks on the fly.

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.
