perf tools: Synthetize the targeted process

Browse Source 
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.
