Evan Lezar b8389283d5 Extract options from default runtime if runc does not exist
This change updates the logic to populate the options for the
nvidia runtime configs added to containerd or crio from a default runtime
if this is specified and a runc entry is not found.

This allows the default runtime values for settings such as SystemdCgroup
to be applied correctly.
