chrootarchive: don't create parent dirs outside of chroot

Browse source 
If chroot is used with a special root directory then create
destination directory within chroot. This works automatically
already due to extractor creating parent paths and is only
used currently with cp where parent paths are actually required
and error will be shown to user before reaching this point.
