Same as netinet/in.h, the netinet/ip6.h on FreeBSD requires
sys/types.h to be included first. So, adding a similar guard.
We do have FreeBSD CI these days, but it is still nice to have
a more clear error message.
Fixes: b2befd5bb2db ("sparse: Add guards to prevent FreeBSD-incompatible
#include order.")
