vd_lavc: sort hwdecs without hwdevices last for autoprobing

For hwdecs without devices we can't get instant feedback during probing
whether the hwdec can possibly work or not, so we definitely want to try them last.
Independently this would also have solved the issue addressed by the previous commit.
