diff-files --raw: show correct post-image of intent-to-add files
The documented behavior of `git diff-files --raw` is to display
[...] 0{40} if creation, unmerged or "look at work tree".
on the right hand (i.e. postimage) side. This happens for files that
have unstaged modifications, and for files that are unmodified but
stat-dirty.
For intent-to-add files, we used to show the empty blob's hash instead.
In c26022ea8f5 (diff: convert diff_addremove to struct object_id,
2017-05-30), we made that worse by inadvertently changing that to the
hash of the empty tree.
Let's make the behavior consistent with files that have unstaged
modifications (which applies to intent-to-add files, too) by showing
all-zero values also for intent-to-add files.
Accordingly, this patch adjusts the expectations set by the regression
test introduced in feea6946a5b (diff-files: treat "i-t-a" files as
"not-in-index", 2020-06-20).
