During the 1st stage build of multi-stage build, when
run swupd os-install, the swupd state data are saved to
/swupd_state, which will not be copied to the target.
So we do not need to remove swupd state data.

Use a docker multistage build technique to create a container
that only has the os-core bundle, providing the minimal content
required for constructing any Clear Linux base container.
Any containers that use this as a common base and still require
additional Clear Linux content will also need to perform a
multistage build since the os-core container does not include
swupd.
