ref-manual: split CentOS-7 and CentOS-8 reqs

CentOS-7 has different requirements than the much
newer CentOS-8. Add a section for CentOS-8 and
make the old section CentOS-7 specific.

NOTE: at the time this was written, the 'fop'
package is not yet available in epel-8. As
a Fedora packager, that will change.
