perf report: Always honor callchain order for inlined nodes

Browse Source 
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.
