Thanks a huge, Dima! I need to think about this. While I believe
it's correct way for zdtm inside CRIU, it's known that we're
running zdtm on its own (as a standalone framework) as far
as I remember for pcs7 testing. So maybe indeed we need to
find workaround to force "make test" operate as it were
before... Gimme a couple of hours.
