tests: check decoding of rtmsg netlink attributes

Browse Source 
* tests/nlattr_rtmsg.c: Include <netinet/in.h> and <arpa/inet.h>.
(LWTUNNEL_ENCAP_NONE, RTA_ENCAP_TYPE): New macros.
(main): Check decoding of RTA_DST, RTA_OIF, RTA_METRICS, RTA_MULTIPATH,
RTA_CACHEINFO, RTA_MFC_STATS, RTA_VIA, and RTA_ENCAP_TYPE.
