docker wrapper and rootless docker

Build steps with a container image specified (docker wrapper) have an hidden last step: Fix directory ownership.

This can be seen only with VERBOSE messages.

While this is good for standard docker installation (but not required if people extend docker options with --uid $UID), it BREAKS if docker is running rootless.

Because the step uses busybox to chown the directory, assuming docker is rootful.

Is there any possible configuration to skip this step? It's not required in rootless
