Ensure consistent construction order for libs

This change ensures that nvnllib and devicelib are constructed
before these are used to construct infolib.

 * Use : as a config --set list separator. This fixes a bug in modifying lists in the config file with the `nvidia-ctk config` command.
 * Add `RUNTIME_CONFIG_OVERRIDE` (`--runtime-config-override`) to the `nvidia-ctk runtime configure` command and the toolkit container to allow for containerd runtime options to be set directly. This can be used to override the `SystemdCroup` option explicitly, for example.
+* Ensure consistent construction of libraries for CDI spec generation.
