[CRIU] [PATCH cr 07/11] restore: restore sid of task which isn't leaders and isn't a child of init (v4)

[Andrey Vagin]

It's sign, that a parent has been changed sid after forking a child.
We should know a sid with which a process was born, because in a processes
chain, more then one process might change SID.

v2: fix names of variables
v3: prevent rewriting of born_sid
v4: Abort the restorer with error message if a born_sid can't be determing.
