[CRIU] [PATCH 5/6] options: Add --const-tty option

[Cyrill Gorcunov]

In pretty rare cases a user might want the crtools
to not migrate dumped slave peers but restore them
on existing locations.

A case for that is two tasks where one opens master
peer and second opens a slave peer, but only second
task is dumped.
