test: Accept different criu test failure error message

Current Debian testing got a new podman version which changed the error
message when `criu` is not available, to "failed to check for criu
version: "criu": executable file not found in $PATH".

This is a bit less nice than the previous version requirement, but still
clear enough, so accept it.
