So that we have the boilerplate in the preparation method, instead of
open coded in tools wanting the reporting when the exec fails.

Getting unwieldly long, for this app domain should be descriptive enough
and the use of __ to separate the class from the method names should
help with avoiding clashes with other code bases.

The tail position of the event buffer should only be modified after
actually use that event.
If not the event buffer could be invalid before use, and segment fault
occurs when invoking perf top -G.

Adding new common function to create evlist with default event. It

The new test__task_exit() test runs a simple "/usr/bin/true" workload and then
checks whether the number of EXIT event is 1 or not.
