src: Allow list single stateful object

Currently the stateful objects can only be listed in groups. With this
patch listing a single object is allowed:

$ nft list counter filter https-traffic
table ip filter {
	counter https-traffic {
		packets 4014 bytes 228948
	}
}

$ nft list quota filter https-quota
table ip filter {
	quota https-quota {
		25 mbytes used 278 kbytes
	}
}
