perf_event__synthesize_mmap_events does not create anonymous mmap events even though the kernel does. As a result an already running application with dynamically created code will not get profiled - all samples end up in the unknown bucket. This patch skips any entries with '[' in the name to avoid adding events for special regions (eg the vsyscall page). All other executable mmaps are assumed to be anonymous and an event is synthesized.
