Subject: [PATCH] perf tests: Disable breakpoint accounting test for powerpc

We disable this test as instruction breakpoints (HW_BREAKPOINT_X)
are not available for powerpc.

Before applying patch:

21: Breakpoint accounting                                 :
--- start ---
test child forked, pid 3635
failed opening event 0
failed opening event 0
watchpoints count 1, breakpoints count 0, has_ioctl 1, share 0
test child finished with -2
---- end ----
Breakpoint accounting: Skip

After applying patch:

21: Breakpoint accounting                                 : Disabled
