[efi] Enable NET_PROTO_IPV6 by default
IPv6 PXE was included in the UEFI specification over eight years ago,
specifically in version 2.3 (Errata D).
http://www.uefi.org/sites/default/files/resources/UEFI_Spec_2_3_D.pdf
When iPXE is being chainloaded from a UEFI firmware performing a PXE
boot in an IPv6 network, it is essential that iPXE supports IPv6 as
well.
I understand that the reason for NET_PROTO_IPV6 being disabled by
default (in src/config/general.h) is that it would cause certain
space-constrained build targets to become too large. However, this
should not be an issue for EFI builds.
It is also worth noting that RFC 6540 makes a clear recommendation
that IPv6 support should not be considered optional.
