NM Binder Perf: Correctly invalidate mKnownNotifications in cancelAll()

Namely, only notifications associated to the current package and user. This won't make a difference for most apps, but was overtriggering for delegates or apps with INTERACT_ACROSS_USERS permissions.

Also made all paths that call enqueue/cancel update this structure, so weird cases are covered.
