The ompt/tasks/task_types.c testcase did not test untied tasks properly. Now, frame addresses are tested and two scheduling points are added at which the task can switch to another thread. Due to scheduling effects, the frame address could be NULL.

This needed a restructure of the  way OMPT callbacks are called. `__ompt_task_finish()` now as an extra parameter, whether a task is completed. Its invocation has been moved into `__kmp_task_finish()`. Thus, the order of the writes to the frame addresses is not subject to scheduling effects anymore.
