Subject: [PATCH] src/coap_io.c: fix definition of struct in*_pktinfo

On some systems we must the struct in_pktinfo and in6_pktinfo defining
by ourself. But on POSIX systems the definition is made by the header
netinet/in.h, so check if there is a flag HAVE_NETINET_IN_H been set and
skip the self made definition.
