mime.bbclass: rework

* add a short descriptions of class' use case
* remove checks for update-mime-database - it can be considered available:
  * at build time by PACKAGE_WRITE_DEPS
  * at package upgrade by RDEPENDS chain
    pkg -> shared-mime-info-data -> shared-mime-info
* simplify (accelerate?) xml file extension detection
* run update-mime-database once only at image creation to avoid expensive
  redundant operations
* allow shared-mime-info to inherit mime.bbclass by avoiding circular
  dependencies
