Include the generic.ins file on the s390 boot iso, so it's directly bootable
on an LPAR. The full iso already had generic.ins included.

...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.
