Add a test for parsing a non-sample event when there is more than one selected event but no sample_id_all bit set. The test fails because of a bug in the evlist logic. That is fixed in a separate patch.

* This function tests parsing data produced on kernel's that do not support the

|
* sample_id_all bit. Without the sample_id_all bit, non-sample events (such as
|
|
* mmap events) do not have an id sample appended, and consequently logic
|
|
* designed to determine the id will not work. That case happens when there is

* more than one selected event, so this test processes three events: 2
|
|
* attributes representing the selected events and one mmap event.
|
|
*
|
|
* Return: %0 on success, %-1 if the test fails.
