linux_container: fork an init process in a new set of namespaces
...
Use namespace.Exec() and namespace.Init() to execute processes in CT.
Now an init process is actually executed in a new container. This series
doesn't change code about creating containers, it only reworks code according
with new API.

This patch changes the incorrectly named functions GetPasswdFile,
