This is weirdly specific. Can we accomplish the same thing with existing
tools?

E.g., could:

  git cat-file --batch-all-objects --batch-check='%(objectname)' |
  shuffle |
  head -n 100

do the same thing?

I know that "shuffle" isn't available everywhere, but I'd much rather
see us fill in portability gaps in a general way, rather than
introducing one-shot C code that needs to be maintained (and you
wouldn't _think_ that t/helper programs need much maintenance, but try
perusing "git log t/helper" output; they have to adapt to the same
tree-wide changes as the rest of the code).
