[libvirt] [jenkins-ci PATCH v2 3/8] guests: Add CentOS 8

[Fabiano Fidêncio]

This commit allows calling `lcitool install libvirt-centos-8`.

`lcitool update libvirt-centos-8 $project` does *not* work as:
- EPEL repository is only enabled for CentOS 7;
  - The reason EPEL is needed because of some base packages (as screen);
- There's no task to enable PowerTools repository;
  - PowerTools is needed because the development packages are
    distributed via this repo;
- There's *no* project supported;
