Run `gem update --system` in hyrax-base & set ACL

Updates rubygems and bundler in the hyrax-base image, with the ability to specify a version in the event of bundler bugs.
Also adds the acl package and uses it to set default permissions for the bundle directory. This is needed because prior to this change the bundle directory is empty and will use the non-root user permissions when installing gems in a later layer. Now root creates files during the system update, causing permission errors when a regular user attempts to install additional gems.
