src: add comment support when adding tables
Adds userdata building logic if a comment is specified when creating a
new table. Adds netlink userdata parsing callback function.
Relies on kernel supporting userdata for nft_table.
Example:
> nft add table ip x { comment "test"\; }
> nft list ruleset
table ip x {
comment "test"
}
