[PATCH v4 7/9] submodule--helper: convert "status" to its own "--super-prefix"

[Ævar Arnfjörð Bjarmason <avarab@xxxxxxxxx>]

As with a preceding commit to convert "absorbgitdirs", we can convert
"submodule--helper status" to use its own "--super-prefix", instead of
relying on the global "--super-prefix" argument to "git" itself. See
that earlier commit for the rationale and background.
