The usual early machinery of Git is to change the directory to
the top level of the working tree and pass the actual path inside
the working tree as `prefix` to the command being run.
This is the case both for commands written in C (where the
prefix is passed into the command in a function parameter) as
well as in git-submodule.sh where the setup code runs
wt_prefix=$(git rev-parse show-prefix)
cd_to_top_level
So the prefix passed into the `submodule--helper list` is actually
the relative path inside the working tree, but we were not using
the standard way of passing it through.
Adhere to Gits standard of passing the relative path inside the
working tree by passing it via -C. This is more readable for future
readers of the code.
We do not need to pass it for `submodule foreach` as that command
doesn't take further arguments ('$@') to operate on a subset of
submodules, such that it is irrelevant for listing the submodules.
The computation of the displaypath ('Entering <path>') is done
separately there.
