include sys/types.h in netfilter headers exported to userspace.

When using 2.6.25 kernel headers iptables fails to compile like below
/scratch/oe/build/eglibc/tmp-omap5912osk/staging/arm-angstrom-linux-gnueabi/usr/include/linux/netfilter.h:40: error: expected specifier-qualifier-list before '__u32'
This patch includes sys/types.h in userspace netfilter headers so __u32 definition is resolved.

+    netfilter: Move linux/types.h inclusions outside of #ifdef __KERNEL__
+    
+    Greg Steuck <greg@nest.cx> points out that some of the netfilter
+    headers can't be used in userspace without including linux/types.h
+    first. The headers include their own linux/types.h include statements,
+    these are stripped by make headers-install because they are inside
+    #ifdef __KERNEL__ however. Move them out to fix this.
+    
+    Reported and Tested by Greg Steuck.
