Commit Message

Delta update requires artifacts in Zchunk format. The class adds two new
IMAGE_FSTYPES:

- zck: this is the artifact in zchunk format and should be made
  available for downloading.
- zck.zckheader : this is just the header extracted from the zck file.
  This file should be added to the SWU for delta update.
