Subject: [PATCH 2/2] Add missing <sys/types.h> include

From: Thomas Petazzoni <thomas.petazzoni@...e-electrons.com>

The u_intXX_t types are defined in <sys/types.h>, so it should be
included before using those types. Otherwise, with certain C
libraries, the build fails with:

In file included from ../include/iptables.h:4:0,
                 from m_ipt.c:18:
../include/iptables_common.h:47:16: error: unknown type name ‘u_int32_t’
 #define __le32 u_int32_t
