perf report: Always honor callchain order for inlined nodes
So far, the inlined nodes where only reversed when we built perf against libbfd. If that was not available, the addr2line fallback code path was missing the inline_list__reverse call. Now we always add the nodes in the correct order within inline_list__append. This removes the need to reverse the list and also ensures that all callers construct the list in the right order.
