Remove vyos_facts neighbors integration tests (#27957)

The tests rely on setting the lldp IP on the management interface.
However, the IP discovered is the private IP of the node, and tests
require accessing it via Nodepool node public IP.
Removing that test for now to get CI green again, we'll reasses once we
release 2.4.
