Change SDL backend to restore the original GL context. This allows Qemu's virtio-gpu to support new virglrenderer async-fencing feature for Virgl contexts, otherwise virglrenderer's vrend creates a fence-sync context on the Qemu's main-loop thread that erroneously stays in-use by the main-loop after creation, not allowing vrend's fence-sync thread switch to this new context that belongs to it.
