Subject: [PATCH 01/41] perf-with-kcore.sh: Always allow fix_buildid_cache_permissions

From: Adrian Hunter <adrian.hunter@...el.com>

The user's buildid cache may contain entries added by root even if root
has its own home directory (e.g. by using perfconfig to specify the same
buildid dir), so remove that validation.
