perf machine: Fix the value used for unknown pids
The value used for unknown pids cannot be zero because that is used by
the "idle" task.
Use -1 instead. Also handle the unknown pid case when creating map
groups.
Note that, threads with an unknown pid should not occur because fork (or
synthesized) events precede the thread's existence.
