[PATCH 05/19] gnome-help.bbclass: Handle gnome-help files with new distro feature 'helpfiles'

["Andreas Müller" <schnitzeltony@gmail.com>]

Now that we can build gnome help files, let our users decide what to do with
them:

if 'helpfiles' not in DISTRO_FEATURES
    delete all help contents during install
else
  if PACKAGE_NO_HELP_SPLIT == 1
      pack all help files to ${PN}-help
  else
      pack help files to ${PN}-help-<lingua>
