Extract deb and rpm packages to single image

This change swithces to using a single image for the NVIDIA Container Toolkit contianer.
Here the contents of the architecture-specific deb and rpm packages are extracted
to a known root. These contents can then be installed using the updated installation
mechanism which has been updated to detect the source root based on the packaging type.
