[PATCH 2/4] tests: add check for NETLINK_NETFILTER parser

[Chen Jingpiao]

* tests/netlink_netfilter.c: Include <netinet/in.h>, <arpa/inet.h>
and <linux/netfilter/nf_tables.h>.
Replace "netlink.h" with "test_netlink.h".
(NFNL_SUBSYS_NFTABLES, NFT_MSG_NEWTABLE): New macros.
(test_nlmsg_done, test_nfgenmsg): New functions.
(main): Use them.
