[CRIU] [PATCH 1/5] test_msg(): avoid recursion

[Kir Kolyshkin]

In (highly unlikely) case localtime() failed, test_msg() calls
pr_perror() which is a wrapper around test_msg() so we're
calling ourselves, which can lead to infinite recursion if
localtime() keeps failing. Use fprintf() here to avoid this.
