src: allow to specify the default policy for base chains
The new syntax is:
nft add chain filter input { hook input type filter priority 0\; policy accept\; }
but the previous syntax is still allowed:
nft add chain filter input { hook input type filter priority 0\; }
this assumes default policy to accept.
If the base chain already exists, you can update the policy via:
nft add chain filter input { policy drop\; }
