Add tests to create vlan/ipvlan/macvlan over a bond interface and move
them to a separate network namespace. Verify that the upper link state
correctly reflects the lower-layer link state.
# ./rtnetlink.sh -t "kci_test_vlan kci_test_ipvlan kci_test_macvlan"
PASS: vlan link state correct
PASS: ipvlan link state correct
PASS: macvlan link state correct
