linux-firmware: Upgrade to 20241017 and allow compressing firmware

The new 20241017 version contains some breaking changes
regarding firmware file deduplication.

Disable running check_whence.py in copy-firmware.sh to avoid
build issues. Instead, assume that WHENCE as accepted into
release tarballs is correct.

The kernel, dracut and systemd all support compressed firmware
files. Allow compressing them either as xz or zst which allows
significant disk space savings.

Ship non-compressed firmware as default.
