Evan Lezar 3e7acec0b4 Add nvidia-ctk config generate-default command
This change adds a CLI command to generate a default config.
This config checks the host operating system to apply specific
modifications that were previously captured in static config
files.

These include:
* select /sbin/ldconfig or /sbin/ldconfig.real depending on which exists on the host
* set the user to allow device access on SUSE-based systems
