perf test: S390 does not support watchpoints in test 22
S390 does not support the perf_event_open system call for
attribute type PERF_TYPE_BREAKPOINT. This results in test
failure for test 22:
[root@s8360046 perf]# ./perf test 22
22: Watchpoint :
22.1: Read Only Watchpoint : FAILED!
22.2: Write Only Watchpoint : FAILED!
22.3: Read / Write Watchpoint : FAILED!
22.4: Modify Watchpoint : FAILED!
[root@s8360046 perf]#
Add s390 support to avoid these tests being executed on
s390 platform:
[root@s8360046 perf]# ./perf test 22
[root@s8360046 perf]# ./perf test -v 22
22: Watchpoint : Disabled
[root@s8360046 perf]#
