----------------------------------------------------------------------
Add a flag needs_auxtrace_mmap to record whether an auxtrace mmap is needed, in preparation for correctly determining whether or not an auxtrace mmap is needed.
The change was added in the mainline [1], but it was deleted when upstream openEuler for fixes build error. openEuler OLK-5.10 now has merge evsel->needs_auxtrace_mmap. Therefore, backport this modification to OpenEuler OLK-5.10.
