dracut renamed this module so the files were being removed from the
install.img (BUT not from the initramfs). They are necessary for the
shutdown eject feature to work.
Related: rhbz#1805405
The eject utility moved into util-linux and the package was dropped, but
since the runtime-cleanup template is using `removefrom util-linux
--allbut` it was never added to the boot.iso after the move.
This adds it to the list of binaries to keep from util-linux.
Resolves: rhbz#1805405
...turns out you can't just have a single template file, because lorax
just picks a single directory and expects all the data it needs to be
there. Sigh.
So this adds all the rest of the files, plus some Makefile machinery for
generating a tarball and updating the specfile after you've checked in
changes. See README for details.
