neotest: info-local: Fix NIC display for virtio devices

For virtio NICs /sys/class/net/<NIC>/device lead to $pcidev/virtioX, not just $pcidev, e.g.:

	$ realpath /sys/class/net/ens3/device
	/sys/devices/pci0000:00/0000:00:03.0/virtio0

and we were extracting virtio0 instead of 0000:00:03.0 as PCI device identifier.

-> Fix it by recognizing and stripping /virtioX suffix.
