  Rework the logic for installing the pkg(8) configuration.

  'quarterly' package sets do not exist for head, so explicitly
  install the 'latest' configuration file there.  Otherwise,
  fall back to the original conditional evaluation to determine
  if the 'latest' or 'quarterly' configuration file should be
  installed.
