Some functions like ebiten.SetCursorMode use `running` to detect whether the game starts or not. If the game starts, the main thread must exist, but there was a timing when `running` was true but the main thread didn't exist. This change fixes this issue by changing the timing to call `setRunning(true)` after the main thread initialization and before `initOnMainThread`. `initOnMainThread` assumes that `running` is true. Closes #2742
