The docroot fix from PR#240 worked fine for default servers. But as soon as one uses vhosts this broke as the vhosts were created under the docroot in /var/www/html rather than the better /var/www. Fix this by differentiating between docroot and wwwdir. Further allow to override both in Red Hat-style configs. The override allows to reuse this formula for the softwarecollections rpms.
