copr-backend: don't delay mdadm/lvm2 installation

This is needed when we run the playbook against the `*-temp` hostname;
while we don't have the volumes in hand, we still want to install all
the tooling early.  This minimizes the risk that the subsequent volume
attachment do not automatically construct the RAIDs (vg).
