With this patch if KIWI is running inside the buildservice the
/.buildenv file is copied from the build environment to the build
root of KIWI. At installation time some packages test the existance
of this file in order to know if they are being installed inside the
buildservice or not.
Fixes#421
This commit fixes the validation of an existing root directory
for the command 'system build'. System build used to create the root
directory before performing the root existance check, thus the
check was always failing in any case. The root directory is created
inside the RootInit class within the 'create' method.
Fixes#349
Creating a new root init with a shared location which already
provides directories of the system failed on init of those
directories. Only create the not yet existing directories
