update_engine: De-duplicate zlib blocks of squashfs images
Having duplicate zlib blocks in the squashfs image (e.g. from two
hard linked files) will cause problems for processing puffin. Recently
ARC++ image introduced two files that where hard linked of each other
and this caused the squashfs parsing algorithm fail and the ARC++ image
does not get splitted into smaller files. Hence we got massive OOM and
Timeout problems in the builders. This CL, simpliy removes duplicate
zlib blocks when constructing the list of such items.
