Brian Goff aedb9451a5 Fix issue with cp to container volume dir ...

In some cases, attempting to `docker cp` to a container's volume dir
would fail due to the volume mounts not existing after performing a
bind-mount on the container path prior to doing a pivot_root.

This does not seem to be effecting all systems, but was found to be a
problem on centos.
The solution is to use an `rbind` rather than `bind` so that any
existing mounts are carried over.

The `MakePrivate` on `path` is no longer neccessary since we are already
doing `MakeRPrivate` on `/`.
