src: remove deprecated code for export/import commands

Update parser to display this error message:

 # nft export json
 Error: JSON export is no longer supported, use 'nft -j list ruleset' instead
 export json
 ^^^^^^^^^^^^

Just like:

 # nft export vm json
 Error: JSON export is no longer supported, use 'nft -j list ruleset' instead
 export vm json
 ^^^^^^^^^^^^^^^
