dracut-install: Add support for compressed firmware files 

The upcoming kernel will have a support for loading compressed
firmware files, and this patch corresponds to that kernel change.
When a firmware file with the extra .xz extension is found, dracut
copies to initrd as fallback.  Since initrd itself is compressed, the
file is uncompressed in initrd beforehand.
