difftool: handle unmerged files in dir-diff mode
When files are unmerged they can show up as both unmerged and
modified in the output of `git diff --raw`. This causes
difftool's dir-diff to create filesystem entries for the same
path twice, which fails when it encounters a duplicate path.
Ensure that each worktree path is only processed once.
Add a test to demonstrate the breakage.
