perf tools: Synthetize the targeted process
Don't forget to also synthetize the targeted process from perf record or we'll miss its dso in the events and then we won't be able to deal with its build-id. We are missing it because it is created after the existing synthetized tasks but before the counters are enabled and can send its mapping event.
