nodesuspend: report unsupported if systemd & pm-utils aren't available

Browse Source 
When libvirtd is run inside a container it is normal that neither
systemd nor pm-utils will be available. In this case there is no way to
suspend the host, so libvirt should just report the feature unsupported
instead of raising an error.
