r/pxe: Add directory for serving kickstarts

Now that kickstart scripts are generated from templates by a Jenkins
job, they need to be stored somewhere besides Gitea.  It makes sense to
serve them from the PXE server, since it's involved in the installation
process anyway (at least for physical machines).   Thus, we need a path
where the generated files can be uploaded by Jenkins and served by
Apache.
