sle15: Do not install distro version of open driver when building one from CUDA

The SUSE's version of the NVIDIA driver has 'Supplements:' on PCI device
IDs. These cause the open driver to be installed on machines which happen
to have a matching NVIDIA card when the kernel is installed.
Use a not-well-known trick to work around this.
