[PATCH][v2 05/10] insane.bbclass: introduce a warning for mime missing in inherit

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

* looking through layers it looks that usage of mime.bbclass is somewhat
  orphaned
* now that update-mime-database is called once only at image creation time,
  costs of mime.bbclass are limited
