tst: Provide test for sched_rr_get_interval
This change adds new test to assess sched_rr_get_interval's functionality. To be more specific - following use cases are checked: - If the read interval is correct - If the proper ABI is used - to check if adjacent data is not overwritten Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
