Fix thread index values (#287)

* Update PTL

- PTL submodule waits for threads to start before proceeding

* Initialize perfetto after init_bundle

- perfetto thread creation after pthread_create wrapped

* backtrace component update

- exclude gotcha call-tree

* callchain component update

- callchain::get sorts based on timestamp
- callchain::sample supports duplicate IPs (recursion)

* Bump version to 1.10.1
