This test uses systemtap to replace random parasite command on
invalide command. The parasite code received this command and should
rollback itself. CRIU didn't recived ack, should understand that
something wrong and exits. The systemtap inverts exit code of criu.

"zdtm.sh -d" is used for executing tests and testing that the state of
processes don't corrupted.

criu should be compiled without optimizations (make DEBUG=1)
