perf x86 test: Add hybrid test for conflicting legacy/sysfs event
The cpu-cycles event is both a legacy event and declared in
/sys/devices/cpu_core/events/cpu-cycles. The cycles event is a legacy
event but with no sysfs version.
Add a test that the sysfs version is preferred to the legacy for
cpu-cycles, while for cycles we use the legacy version.
