[PATCH 02/20] perf env: fix sibling_dies memory leak

[Riccardo Mancini]

ASan reports a memory leak in perf_env while running the perf test
"41: Session topology", caused by sibling_dies not being freed.

This patch adds the required free.

Fixes: acae8b36cded0ee6 ("perf header: Add die information in CPU topology")
