Virgl relies on callbacks provided by the OpenGL display, and such a display may rely on eglMakeCurrent. eglMakeCurrent will fail if the given context is current to some other thread. The easiest way to avoid such a failure is to call the OpenGL display in a single thread. As all operations except virtio_gpu_virgl_reset happens in the main thread, this change makes virtio_gpu_virgl_reset happen only in the main thread.
