Set volume NeedsCopyUp to false iff data was copied up
Currently Docker copies up the first volume on a mountpoint with data. Fixes: https://github.com/containers/podman/issues/12714 Also added NeedsCopyUP, NeedsChown and MountCount to the podman volume inspect code. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
