on UEFI hardware.

Previously there was no way to set the 802.1Q VLAN identifier, despite
support for vlantag in the net module. The only location vlantag was
being populated was from PXE boot and only for Open Firmware hardware.
This commit allows users to manually configure VLAN information for any
interface.
Example usage:
grub> net_ls_addr
efinet1 00:11:22:33:44:55 192.0.2.100
grub> net_set_vlan efinet1 100
grub> net_ls_addr
efinet1 00:11:22:33:44:55 192.0.2.100 vlan100
grub> net_set_vlan efinet1 0
efinet1 00:11:22:33:44:55 192.0.2.100

VLAN configuration seems to have never worked on little-endian systems.
This is likely because VLANTAG_IDENTIFIER is not byte-swapped before
copying into the net buffer, nor is inf->vlantag. We can resolve this by
using grub_cpu_to_be16{_compile_time}() and its inverse when copying
VLAN info to/from the net buffer.
