net-tools: fix field with incomplete type error

Update 0002 patch to match the one sent as a pull request. The previous
one introduced a new problem that has been addressed in the new version.

Some Linux headers included in certain toolchains may not have an
updated linux/if_tunnel.h which includes linux/ip.h, so we need to
include it unconditionally otherwise linux/if_tunnel.h will use the
struct iphdr before being defined and the compilation will fail in this
way:

In file included from iptunnel.c:33:0:
/usr/include/linux/if_tunnel.h:37:16: error: field 'iph' has incomplete
type
  struct iphdr  iph;
                  ^
