nftables: rearrange files and examples

Concatenate all family/hook examples into a single one by means of includes.

Put all example files under examples/. Use the '.nft' prefix and mark
them as executable files. Use a static shebang declaration, since these
are examples meant for final systems and users.

While at it, refresh also the sets_and_maps.nft example file and also
add the 'netdev-ingress.nft' example file.
