Doug Bryant 8df8e9cb6e cmd/containerboot: rate-limit IPN bus netmap notifications

CPU profiling a containerboot subnet router on a large tailnet showed
roughly 40% of CPU spent in serveWatchIPNBus JSON-encoding the full
netmap on every update. containerboot only reads SelfNode fields from
those notifications (and does a peer lookup when TailnetTargetFQDN is
set), so it does not need every intermediate netmap delta.

Set ipn.NotifyRateLimit on all three WatchIPNBus calls so netmap
notifications are coalesced to one per 3s. Initial-state delivery is
unaffected since the rateLimitingBusSender flushes the first send
immediately.

Updates #cleanup
