scp in openssh 8.7 will change to use sftp protocol. See
https://github.com/openssh/openssh-portable/pull/194 for details.
This enables the sshd internal-sftp implementation so that newer scp
versions will continue to work as expected. Note that the sshd service
is only running during the installation if inst.sshd is passed on the
kernel cmdline.

...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.
