perf x86 test: Update hybrid expectations

perf x86 test: Update hybrid expectations

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: a24d9d9dc096fc0d ("perf parse-events: Make legacy events lower priority than sysfs/JSON")
