fix#1476
If containerA shares namespace, say ipc namespace, with containerB, then
its ipc namespace path would be the same as containerB and be stored in
`state.json`. Exec into containerA will just read the namespace paths
stored in this file and join these namespaces. So, if containerB has
already been stopped, `docker exec containerA` will fail.
To address this issue, we should always save own namespace paths no
matter if we share namespaces with other containers.

we need to ensure that that usecase works as well as the out of process
one.
