33217: vcs_info: use `--ignore-submodules=dirty` with diff/diff-index

This will detect changes to submodules from the superproject's
perspective, e.g. after `git rm submodule`.

>From GIT-DIFF-INDEX(1)/GIT-DIFF(1):

    Using "dirty" ignores all changes to the work tree of submodules,
    only changes to the commits stored in the superproject are shown
    (this was the behavior until 1.7.0).
