[libvirt] [jenkins-ci PATCH] guests: Install EPEL on CentOS 7 container

[Fabiano Fidêncio]

Since commit d63d6a59cc we're installing EPEL on CentOS7 in order to
have both "ninja" and "python36-*" packages in the system.

However, we've forgot to add the very code to the lcitool so the
containers would also have EPEL release installed.
