Fix loading of util/debian.rb for custom facts

requirering the facter/util/debian.rb module causes
puppet warnings on wheezy hosts, and custom facts like
`$::debian_codename` cannot be evaluated.

    warning: Could not load fact file
      /srv/dev/projects/puppet/shared-modules//apt/lib/facter/debian_nextcodename.rb:
      no such file to load -- facter/util/debian

Removing the require line solves this.
