Add a test case to assert that the skb->pkt_type which was set from the BPF
program is retained from the netkit xmit side to the peer's device at tcx
ingress location.

This adds simple tests around setting MAC addresses in the different
netkit modes.

Add a bigger batch of test coverage to assert correct operation of
netkit devices and their BPF program management:
# ./test_progs -t tc_netkit
