...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.
This is the initial commit for this package. We're just keeping the
templates here in dist-git so for the purposes of posterity I'm starting
with the runtime-install.tmpl from current rhel-8.0 lorax. This way
every change made to the template(s) will be in the git repo. Hooray!
I know we're going to make changes to runtime-install.tmpl, and I
_suspect_ we'll make changes to runtime-postinstall.tmpl and
runtime-cleanup.tmpl, so they're in the specfile (but commented out).
