From: Thomas Richter <tmricht@linux.vnet.ibm.com>
The s390x CPU sampling and measurement facilities do not support perf events of type PERF_TYPE_BREAKPOINT. The test cases are executed and fail with -ENOENT due to missing hardware support.
Disable the execution of both test cases based on a platform check. This is the same approach as done for PowerPC.
