rbutil: Fix TTS "waiting for engine" appearing randomly.

QProgressDialog shows / hides itself automatically based on the progress
value set, so calling hide() directly doesn't prevent the dialog from
showing itself.

Change the logic to set a value instead. Fixes the progress dialog
sometimes appearing in situations where it wasn't used at all.
