juno-r2 - arm64: ltp-syscalls-tests: * perf_event_open02

perf_event_open02 is an intermittent failures on Juno, x86 and x15.

Here is the LAVA job showing perf_event_open02 failed 2 times out of 20 iteration. https://lkft.validation.linaro.org/scheduler/job/106571#L1605

History of the failure on mainline, https://qa-reports.linaro.org/lkft/linux-mainline-oe/tests/ltp-syscalls-test... stable-rc-4.14, https://qa-reports.linaro.org/lkft/linux-stable-rc-4.14-oe/tests/ltp-syscall... stable-4.4, https://qa-reports.linaro.org/lkft/linux-stable-4.4-oe/tests/ltp-syscalls-te...

We already have a bug on this case, LKFT: 4.9-rc: x86: LTP: perf_event_open02.c:333: test failed (ratio was greater than ) - intermittent failure https://bugs.linaro.org/show_bug.cgi?id=3382

This is already skipped on x15 and Hikey.
