perf test topology: Use !strncmp(right platform) to fix guest PPC comparision check
commit cfd7092c31aed728 ("perf test session topology: Fix test to skip the test in guest environment") added check to skip the testcase if the socket_id can't be fetched from topology info. But the condition check uses strncmp which should be changed to !strncmp and to correctly match platform. Fix this condition check.
