Brian Goff f8ddc00d73 Add refcounts to graphdrivers that use fsdiff
This makes sure fsdiff doesn't try to unmount things that shouldn't be.

**Note**: This is intended as a temporary solution to have as minor a
change as possible for 1.11.1. A bigger change will be required in order
to support container re-attach.
