openstack-placement: make the template more generic

The service macros included with the spec do not work fine on RDO, since
they are not included for Fedora/CentOS. Moving to the scripts used
for both SUSE and RDO.

Also:
- Use apache macros instead of hardcoded directories
- Do not create files under /srv/www on RDO
