update_engine: Change imgdiff/imgpatch to a dummy puffdiff/puffpatch

Currently we never create imgdiff operation as it was never
activated. In near future we will be adding puffdiff and puffpatch
operations which replaces the imgdiff. This CL does not actually adds
puffdiff, but adds a placeholder for it.

BUG=none
TEST=cros_workon_make --board=amd64-generic --test update_engine
