[CRIU] [PATCH cr 1/2] restore: inherit current sid and pgid if a root task isn't a leader

[Andrey Vagin]

crtools can dump a subtree, where a root task isn't a session leader.
E.g: you want to dump "top" and restore it in another terminal.

In this case crtools should not try to restore sid of this task and
all other tasks from this session. All this tasks will inherit sid
from a current process.

All that is true for pgid and a control tty.
