All we need there is a forward declaration for 'union perf_event', so
remove it from there and add missing header directives in places using
things from this indirect include.

And remove unneeded include directives from perf-sys.h to prune the
header dependency tree.
Fixup the fallout in places where definitions were being used without
the needed include directives that were being satisfied because they
were in perf-sys.h.

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]#

We don't have a 'perf test' entry available to test the watchpoint
functionality.
Add a simple set of tests:
- Read only watchpoint
- Write only watchpoint
- Read / Write watchpoint
- Runtime watchpoint modification
Ex.: on powerpc:
$ sudo perf test 22
22: Watchpoint :
22.1: Read Only Watchpoint : Ok
22.2: Write Only Watchpoint : Ok
22.3: Read / Write Watchpoint : Ok
22.4: Modify Watchpoint : Ok
