perf config: Do not consider an error not to have any perfconfig file
While propagating the errors from perf_config(), which were being completely ignored, everything stopped working for people without a ~/.perfconfig file, because the perf_config_set__init() was considering an error not to have a .perfconfig file, duh, fix it by checking the errno after the failed stat() call. It should also not return an error when it says it is ignoring the file, and also a empty file should not return an error either.
