probes: invalidate seen pids on task_rename event Task rename events on Android often signal also a change in the name of the process (think zygote specializing to become an app - this changes both the name of the main thread and the name of the process). Since we don't rescrape a pid once we've ever seen it (modulo incremental state invalidation), we never see the updated names for these processes either. Rescrape any pid which undergoes a task rename by removing it from the seen pids. This is a heuristic (as processes many rename without thread renames and threads which are not the main process often get renamed) but it is a good one as it covers the cases we are most interested in.
