Fix broken cc_update_etc_hosts

Right now, all distros but ubuntu will fail to manage /etc/hosts. 

This is due to the fact that the templates are named:
- hosts.ubuntu.tmpl
- hosts.redhat.tmpl

The config handler is specifically looking for a template with the
given distro name.

This change addresses this issue.
