vpxdec: Check that output width and height != 0

For VP8 it's possible to signal width or height to be 0, but it does not make sense to do so. For VP9 it's impossible. Hence, we most likely have a corrupt stream. Trying to negotiate caps downstream with either width or height as 0 will fail with something like

gst_video_decoder_negotiate_default: assertion 'GST_VIDEO_INFO_WIDTH (&state->info) != 0' failed
