Coordinate in6_pktinfo and ip6_mtuinfo for kernel and glibc
Commit Message
Similarly to what we did for in6_addr, we need a macro
to guard in6_pktinfo and ip6_mtuinfo too.

Mike,
Thank you very much for pushing this. It's almost obvious at this
point given the kind of good coordination we have going with the kernel :-)
Cheers,
Carlos.

Sure, I thought some git hook will automatically write the ChangeLog.
Thanks for fixing it!
