Subject: mkarchiso: place prepared systemd-boot configuration in work
 directory

Keep the prepared `.conf` files in `work_dir` to avoid having to run
them through `sed` twice.

This makes sure the FAT image size calculation is more correct and also
simplifies copying the files m to both ISO 9660 and the FAT image since
the the whole `loader` directory can copied instead of copying
individual files.
