[PATCH 1/1] diff-lib: use worktree mode in diffs from i-t-a entries

["Raymond E. Pasco" <ray@ameretat.dev>]

When creating "new file" diffs against i-t-a index entries, diff-lib
erroneously used the mode of the cache entry rather than the mode of the
file in the worktree. This changes run_diff_files() to correctly use the
mode of the worktree file in this case.

This is a distinct bugfix from the other changes, so I've sent it as a
separate patch also based on v2.28.0.
