Fixes#9960
This adds the output of a "Backing Filesystem:" entry to `docker info`
to overlay, aufs, and devicemapper graphdrivers. The default list
includes a fairly complete list of common filesystem names from
linux/include/uapi/linux/magic.h, but if the backing filesystem is not
recognized, the code will simply show "<unknown>"

This changes the signature of (*Driver).Put for all the drivers implemented.

trees and compares every entry, archive.ApplyLayer() has been extended to
also return the size of the layer changes.
