This enables docker cp and ADD/COPY docker build support for LCOW.
Originally, the graphdriver.Get() interface returned a local path
to the container root filesystem. This does not work for LCOW, so
the Get() method now returns an interface that LCOW implements to
support copying to and from the container.

This changes the graphdriver to perform dynamic sandbox management.
Previously, as a temporary 'hack', the service VM had a prebuilt
sandbox in it. With this change, management is under the control
of the client (docker) and executes a mkfs.ext4 on it. This enables
sandboxes of non-default sizes too (a TODO previously in the code).

This changes the LCOW driver to support both global SVM lifetime and
per-instance lifetime. It also corrects the scratch implementation.
