src: add netdev family support

This patch adds support for the new 'netdev' table. So far, this table allows
you to create filter chains from ingress.

The following example shows a very simple base configuration with one table that
contains a basechain that is attached to the 'eth0':

 # nft list table netdev filter
 table netdev filter {
        chain eth0-ingress {
                type filter hook ingress device eth0 priority 0; policy accept;
        }
 }

You can test that this works by adding a simple rule with counters:

 # nft add rule netdev filter eth0-ingress counter
