ipv4: Fix raw socket lookup for local traffic
inet_iif should be used for the raw socket lookup. inet_iif considers rt_iif which handles the case of local traffic. As it stands, ping to a local address with the '-I <dev>' option fails ever since ping was changed to use SO_BINDTODEVICE instead of cmsg + IP_PKTINFO. IPv6 works fine.
