rtnetlink: add IFLA_GROUP to ifla_policy
[ Upstream commit
db833d40ad3263b2ee3b59a1ba168bb3cfed8137 ]
Network interface groups support added while ago, however
there is no IFLA_GROUP attribute description in policy
and netlink message size calculations until now.
Add IFLA_GROUP attribute to the policy.
