image-prelink: remove assumption of sysconfdir presence

Browse Source 
If sysconfdir is not present in the image filesystem then the temporary
creation of a prelink.conf will fail. Fix this by creating sysconfdir
temporarily if needed beforehand and then remove any directories that
were created afterwards.

fixes: OpenXT OXT-1751
