lttng: Bug 573437: Fix parent process assignment of processes

The ThreadStatusDataProvider now uses the process start time to find
the cached parent process for a given TID (instead of end time). This
fixes the case where the sched_process_free event of the parent is
executed earlier than the child process' sched_process_free.
