Victory music doesn't work in A24 SP. That's because the modal pauses
the game, and pausing the game pauses music.
This has been the case since c9a5d5cee5.
Auto-pausing the game (structree, ...) didn't really happen in the past,
but A24 makes it relatively common, and I think pausing the music is a
bit jarring then, so this simply removes that.
