[PATCH nft,v2 1/2] evaluate: allow get/list/flush dynamic sets and maps via list command

[Pablo Neira Ayuso <pablo@netfilter.org>]

Before:

 # nft list set ip filter untracked_unknown
 Error: No such file or directory; did you mean set ‘untracked_unknown’ in table ip ‘filter’?
 list set ip filter untracked_unknown
                    ^^^^^^^^^^^^^^^^^

After:

 # nft list set ip filter untracked_unknown
 table ip filter {
        set untracked_unknown {
                type ipv4_addr . inet_service . ipv4_addr . inet_service . inet_proto
                size 100000
                flags dynamic,timeout
        }
 }

Add a testcase for this too.
