net/e1000: report VLAN extend capability

The rte_eth_dev_set_vlan_offload function will check vlan rx offload
capability, the i350/i210/i211 nics have vlan extend feature but
DEV_RX_OFFLOAD_VLAN_EXTEND is not set into the capability, that will
cause setting fail. So need to add this capability in
igb_get_rx_port_offloads_capa function.
