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.
