[libvirt] [PATCH] news: Document kernel requirements for virtual networks

After 7431b3eb9a05068e4b libvirt requires "filter", "nat" and
"mangle" tables to exist for both IPv4 and IPv6. This fact was
missed in the news.xml and since we don't have any better place
to advertise that let's update old news.
