Fix bind-mount to point /var/log/containers/libvirt/(qemu)
on the host, via the shared NovaLibvirtLogging attribute.
Remove the nested libvirt/qemu path bind-mount since the outer libvirt
directory is sufficient to hold the qemu logs as well. For that,
bind-mount it with the shared mounts propagation mode.
