[CRIU] Use page-server option in RPC mode

[Hui Kang]

Hi, Pavel,
I did create a pair of socket on the host B. When I send "criu dump" RPC
without "--page-server --port", the RPC call succeed. However, when the RPC
can not talk to the page server in the remote machine. I am wondering if
there is any sample code for page-server in RPC call. Thanks.
