Fix copyUIDGID parameter inversion in Docker compat API

Browse Source 
Docker API's copyUIDGID=true means "preserve UID/GID from archive"
but Podman's internal Chown=true means "chown to container user".
This caused Docker SDK clients to have files incorrectly chowned
to root:root instead of preserving the archive's UID/GID.
