packets: Fix C++ compilation issues when include packets.h
This patch fixes three C++ compilation errors when it includes
"lib/packets.h".
1) Fix in "include/openvswitch/util.h" is to avoid duplicated
named_member__ in struct pkt_metadata.
2) Fix in "lib/packets.h" is because designated initializers are not
implemented in GNU C++ [1].
3) Fix in "lib/util.h" is because __builtin_types_compatible_p and
__builtin_choose_expr are only supported in GCC. I use one solution
for C++ that is type-safe and works at compile time from [2].
