Fix compilation error of m_ipt.c with -Werror enabled

Commit (5a650703d47e10aa386406c855eff5a593b2120b Makefile: make warnings into
errors ) causes the following build error.

gcc -Wall -Wstrict-prototypes -Werror -Wmissing-prototypes
-Wmissing-declarations -Wold-style-definition -O2 -I../include
-DRESOLVE_HOSTNAMES -DLIBDIR=\"/usr/lib\" -DCONFDIR=\"/etc/iproute2\"
-DYY_NO_INPUT   -c -o m_ipt.o m_ipt.c
cc1: warnings being treated as errors
m_ipt.c:72: error: no previous prototype for 'xtables_register_target'
m_ipt.c:361: error: no previous prototype for 'build_st'
make[1]: *** [m_ipt.o] Error 1

This is fixed by adding the prototype in the header include/iptables.h

I am not sure if this is due to something wrong on my build system but I am
using current glibc 2.17.
