I just tried it in a sid chroot (linux-headers-4.9.0-3-amd64 (4.9.30-2)
and nvidia-kernel-dkms (375.66-2)) and it built these files:

Since your module does not give any useful output from modinfo,
something went wrong on your machine - could be dkms or kernel.
Have you tried the nvidia-kernel-source package? Does that build a
usable module?
