perf test parse-events: Without a PMU use cpu-cycles rather than cycles
Without a PMU perf matches an event against any PMU with the
event. Unfortunately some PMU drivers advertise a "cycles" event which
is typically just a core event. Switch to using "cpu-cycles" which is
an indentical legacy event but avoids the multiple PMU confusion
introduced by the PMU drivers. Note, on x86 cpu-cycles is also a sysfs
event but cycles isn't.
