[CRIU] [PATCH 4/5] ovz: preserv ovz module

[nspiridonov]

From: Nikita Spiridonov <nspiridonov at odin.com>

It is usefull at the present moment to have OpenVZ module for
testing purpose. This module basically reuses functionality of
Virtuozzo module and differs only in root_task_pid method. It can
be removed later when Virtuozzo module will be completely compatible
with OpenVZ containers.
