[LTP] [PATCH v4 3/3] Add setsockopt08, CVE-2021-22555

Hi!

I've fixed the failure on Centos with missing IFNAMSIZ but this still
fails to compile on ubuntu xenial because the tst_safe_net.h pull in
netinet/in.h and lapi/ip_tables.h pulls in linux/in.h and on old enough
systems these two headers does not like to be included at the same time.

I'm not sure how to fix this, either we drop the include to
linux/netfilter_ipv4/ip_tables.h completely or we add a configure check
if netinet/in.h and linux/in.h could be included at the same time and
ifdef the linux/netfilter_ipv4/ip_tables.h with that check.

Either way both looks like a hack, if anyone has a better idea please
suggest it.
