Better localhost checking for SSL configuration

The previous patch: https://review.openstack.org/#/c/91144
handles SSL redirection to a hostname but if the $::fqdn facter
variable is "localhost.localdomain" (which is a defualt in some
systems) the manifest will fail to notice this and will add that
hostname to the ServerName apache directive, added a regexp to
avoid any "localhost*" setting.
