This adds a SELinux policy suitable for RHEL/CentOS 7. It assumes the
following:
- public-inbox-httpd and public-inbox-nntpd are running via systemd
on sane ports (119 and 80/8080)
- /var/lib/public-inbox is the location for mainrepos
- /var/run/public-inbox is the location for PERL_INLINE_DIRECTORY
- /var/log/public-inbox is the location for logs
- mail delivery is done via postfix-pipe or public-inbox-watch via
the provided example systemd service
