testsuite: fix the CVE-2014-9112 test case
    
    The fix for CVE was done so that different architectures or memory
    limits give different cpio output;  but all possible error ouputs
    are OK and expected.  Firstly, the testsuite fail was observed on
    ppc64 architecture, thanks dhorak for quick ping.
