[netdevice] Add vlan_tag() to get the VLAN tag of a network device
The iBFT has a VLAN field that should be filled in. Add the
vlan_tag() function to extract the VLAN tag of a network device.
Since VLAN support is optional, define a weak function that returns 0
when iPXE is built without VLAN support.
