Log Message:
-----------
- restructure the use of prebuilt boot images
* adapt to new data structure thus we get rid of
checkAndSetupPrebuiltBootImage, getDefaultPrebuiltDir_legacy
* moved the logic for using a prebuilt version of a boot image
into the image creator code at the level of prepareBootImage
and createBootImage. This saves us one KIWIXML instance
* write one function createImageBootImage which does either
the prepare/create of the boot image or the use of an existing
prebuilt version. reduces some code duplication
