Fix scrubbing behavior on keyguard music transport

This fixes a bug where the music scrub position would snap
back to a previous position. The problem was caused by latency
in the music application responding to scrub position changes.
The latency would mean that we'd get a response periodically
to some historical scrub position change.

Since we can't know when the state will become stable, we
just wait a little bit since the last update change before
continuing to update the scroll position.

In order to keep the music client from falling behind, we
throttle scrub updates.
