Add a new netvf collector that exposes SR-IOV network VF statistics and
configuration via rtnetlink. The collector queries netlink for
interfaces with Virtual Functions and exposes per-VF metrics:
- node_net_vf_info: VF configuration (MAC, VLAN, link state, spoof
check, trust, PCI address)
- node_net_vf_{receive,transmit}_{packets,bytes}_total: traffic counters
- node_net_vf_{broadcast,multicast}_packets_total: packet type counters
- node_net_vf_{receive,transmit}_dropped_total: drop counters
All metrics include a pci_address label resolved from the sysfs virtfn
symlink, enabling direct correlation with workloads that reference VFs
by PCI BDF address (e.g. OpenStack Nova, libvirt, DPDK).
The collector is disabled by default and can be enabled with
--collector.netvf. PF device filtering is supported via
--collector.netvf.device-include/exclude flags.

Bump github.com/jsimonetti/rtnetlink/v2 from 2.1.0 to 2.2.0 - this add the VF stats used for the next commit.

Tested on MT2894 Family [ConnectX-6 Lx] and Ethernet Controller E810-XXV with VFs bound to both kernel driver and vfio-pci driver (for direct assignment to Virtual Machines).
