cache: incorrect flags for create commands

 # nft create table testD
 # nft create chain testD test6
 Error: No such file or directory
 create chain testD test6
              ^^^^^

Handle 'create' command just like 'add' and 'insert'. Check for object
types to dump the tables for more fine grain listing, instead of dumping
the whole ruleset.

Fixes: 7df42800cf89 ("src: single cache_update() call to build cache before evaluation")
