Vitaly Buka d3531fc7f0 [sanitizer] Don't run malloc hooks for stacktraces
Usually when we generated stacktraces the process is in error state, so
running hooks may crash the process and prevent meaningfull error report.

Symbolizer, unwinder and pthread are potential source of mallocs.

crash depending on allocator_may_return_null.
