[#33] Remove outdated patch to OG

  According to OG's issue queue (https://drupal.org/node/2039597),
  the patch to "prevent notice when using 'autocomplete' with
  cardinality = 1" has been applied to the development branch.
  Because this patch is now in the code being downloaded, drush make
  fails to build because it cannot apply this patch cleanly.
