[pve-devel] [PATCH pve-nvidia-vgpu-helper v2 3/5] add pve-nvidia-vgpu-helper and Makefile to make dependency installtion more convenient

[Hannes Duerr <h.duerr@proxmox.com>]

we add the pve-nvidia-vgpu-helper script to make the installation of the
required nvidia vgpu driver dependencies more convenient.
We also add a Makefile to assist in building the debian package and
installing the script
