Subject: support compression and by-hash for .diff/Index files

In af81ab9030229b4ce6cbe28f0f0831d4896fda01 by-hash got implemented as a
special compression type for our usual index files like Packages.
Missing in this scheme was the special .diff/Index index file containing
the info about individual patches for this index file. Deriving from the
index file class directly we inherent the compression handling
infrastructure and in this way also by-hash nearly for free.

Closes: #824926
