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.

Previously, only perm-related bits where preserved when rewriting
FileMode in tar entries on Windows. This had the nasty side effect of
having tarsum returning different values when executing from a tar filed
produced on Windows or Linux.
This fix the issue, and pave the way for incremental build context
to work in hybrid contexts.
