src: Allow to list ruleset without stateful information

Currently only counter and quota have stateful information.

For named counters, packets and bytes are displayed as 0.

Standard list ruleset:

table ip filter {
	counter https {
		packets 161942 bytes 10253353
	}

	chain output {
		type filter hook output priority 0; policy accept;
		counter name tcp dport map { https : "https"}
		tcp dport https counter packets 171211 bytes 10869045
		tcp dport https quota 25 mbytes used 10 mbytes
	}
}

With stateless option, -s:

table ip filter {
	counter https {
		packets 0 bytes 0
	}

	chain output {
		type filter hook output priority 0; policy accept;
		counter name tcp dport map { https : "https"}
		tcp dport https counter
		tcp dport https quota 25 mbytes
	}
}
