perf test topology: Use !strncmp(right platform) to fix guest PPC comparision check

Browse Source 
commit cfd7092c31 ("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.
