If files would be overwritten by the deployment, preserve them in a
separate location on the target so that they can be restored if you
later run devtool undeploy-target.
At the same time, also check for sufficient space before starting the
operation so that we avoid potentially failing part way through.
Fixes [YOCTO #8978].
