automation: don't build guest agent on Fedora
automation: don't build guest agent on Fedora

In Fedora we are retiring ovirt-guest-agent in favor of
qemu-guest-agent.
We are still building windows guest agent on Fedora in order
to be able to generate Windows Guest Tools to be used with Fedora
based ovirt-engine.
