fib_rule, ip6_tunnel, and a whole lot of if_* headers lack the customary _UAPI in the header guard. Without it YNL build can't protect from in tree and system headers both getting included. YNL doesn't need most of these but it's annoying to have to fix them one by one. Note that header installation strips this _UAPI prefix so this should result in no change to the end user.
