Fix _node/$node/_system endpoint

The endpoint is using same handler as a backdoor interface,
which only works for the requests to a local $node.
For rpc calls to the remote nodes, the same as it's done
on rest of /_node endpoints, handle_node_req handler is getting
{badrpc,{'EXIT',normal}} response and fails with invalid_ejson exception.

The change splits stats gathering from stats responding,
allowing to use former on both /_node/$node/_system
and backend's /_system endpoints.
