criu-ns: use os.waitstatus_to_exitcode()

os.WEXITSTATUS() returns the process exit status and it should be used only if WIFEXITED() is true, i.e., the process terminated normally. os.waitstatus_to_exitcode() does the same as os.WEXITSTATUS() but it also handles the case when the process has been terminated by a signal.
