Subject: Add Makefile rules to build nic rom binaries with efi support

"make -C roms efirom" will build rom binaries with EFI support.
They are composed from three images: legacy bios, efi ia32
and efi x64.  So netbooting via SeaBIOS will continue to work
like it does today, and additionally we get network support
for EFI.  This target needs the EfiRom utility (shipped with
edk2) somewhere in the $PATH.
