Yonghong Song 7c128a6bbd tools/bpf: selftests: Add iterator programs for ipv6_route and netlink 
Two bpf programs are added in this patch for netlink and ipv6_route
target. On my VM, I am able to achieve identical
results compared to /proc/net/netlink and /proc/net/ipv6_route.

  $ cat /proc/net/netlink
