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.
