perf db-export: Pass main_thread to db_export__thread()
Calls to db_export__thread() already have main_thread so there is no reason to get it again, instead pass it as a parameter. Note that one difference in this approach is that the main thread is not created if it does not exist. It is better if it is not created because: - If main_thread is being traced it will have been created already. - If it is not being traced, there will be no other information about it, and it will never get deleted because there will be no EXIT event.
