perf record: Allocate area for sample_id_hdr in a synthesized comm event
A previous patch added a synthesized comm event for forked child process but it missed that the event should contain area for sample_id_hdr at the end. It worked by accident since the perf_event union contains bigger event structs like mmap_events. This patch fixes it by dynamically allocating event struct including those area like in perf_event__synthesize_thread_map().
