kata_agent: Allow to use "VirtPath" as volume source for blk devices

Browse Source 
[ port from runtime commit aea29b64b66f75049cb045f9e41dff2becdbebdc ]

When the "PCIAddr" of block device is not available (e.g. cloud-hypervisor), we
allow to use the "VirtPath" as the volume source for creating containers.
