[CRIU] external mountpoint issue for docker

[Bing X]

I didn't get dump.log under /dump dir, based on the screen output, it fails
at run_ns.sh. so the unshare is unsuccessful.

I just wondered if I wrongly modified the root (should be bind, pivotroot,
and unshare). I saw that the sample scripts (run.sh, run_ns.sh) assumes the
current dir is the root should be operated, so I changed it to my docker
root dir (you can see its real dir from mountinfo).

Am I wrong on this?

Sorry for all these tedious work and thanks a lot!
