[3/3] mesos git commit: Windows: Fixed provisioner copy backend build error.

Windows: Fixed provisioner copy backend build error.

The provisioner's `copy` backend has never been supported on Windows,
but we have included it in the build to reduce the number of `#ifdef`s
needed to compile the agent.  If the user attempts to specify a rootfs
on Windows, it will still fail in the containerizer's validation logic.
