SP-T101: Verify PCI device passthrough

Verify passed through PCI devices are visible inside VM. From microvm's
configuration, read the PCI device paths that are supposed to be passed
through, resolve their VENDOR_ID and DEVICE_ID, and then check does
lspci show respective VENDOR_ID:DEVICE_ID combinations inside the VM.
