json: add set statement list support

When listing a set with statements with JSON support, the statements were
ignored.

Output example:

{
  "set": {
    "op": "add",
    "elem": {
      "payload": {
        "protocol": "ip",
        "field": "saddr"
      }
    },
    "stmt": [
      {
        "limit": {
          "rate": 10,
          "burst": 5,
          "per": "second"
        }
      },
      {
        "counter": {
          "packets": 0,
          "bytes": 0
        }
      }
    ],
    "set": "@my_ssh_meter"
  }
}
