src: add 'list maps' support

This commit adds a new command that lists maps:

  # nft list maps [family]

Only the declaration is displayed. If no family is specified, all maps
of all families are listed.

Example:

  # nft list maps

  table ip filter {
          map test {
                  type ipv4_addr : inet_service
          }
  }
  table ip6 filter {
          map test {
                  type ipv6_addr : inet_service
          }
  }
