dl_tarball: Add special support for ice comms ddp fw

This is a firmware package for Intel Ice NIC hardware,
addressing dynamic device personalization for the
communications market.

Intel likes their zips of zips, causing us to have to
perform an extra extraction step to get the zip file
that we want.

Verification:
Success Path
- create a test .lst file with just the entry for the
  intel ice comms ddp firmware in it
- run the dl_tarball.sh script against the test .lst file
- verify that the ice_comms zip file is successfully
  produced in the proper directory
- verify that the wrapper zip file is also left in the
  proper directory
Failure Path
- modify test .lst so that the url to the wrapper zip
  is no longer valid
- verify that the script reports the download error
  properly and handles it properly
