[PATCH] perf test: disable test cases 19 and 20 on s390x

[PATCH] perf test: disable test cases 19 and 20 on s390x

[Thomas Richter]

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.
