The legacy events cpu-cycles and instructions have sysfs event
equivalents on x86 (see /sys/devices/cpu_core/events). As sysfs/JSON
events are now higher in priority than legacy events this causes the
hybrid test expectations not to be met. To fix this switch to legacy
events that don't have sysfs versions, namely cpu-cycles becomes
cycles and instructions becomes branches.

Fixes: a24d9d9dc096 ("perf parse-events: Make legacy events lower priority than sysfs/JSON")
