In 74703a1e4d (2015-09-02, submodule: rewrite `module_list` shell
function in C), "submodule deinit ." was broken.
The original module_list accepted '.' as a pathspec just fine, as it
was using
git ls-files -z --error-unmatch --stage -- "$@" || { custom filtering}
and git ls-files doesn't make a difference between "." and no arguments
there. When using the parse_pathspec function in C, this is a difference
however, when no path matches.
'submodule deinit' asks users to explicitely to give '.' instead of
empty arguments to specify all submodules (as a safety measure?),
so we have to support that as well.
Add a test case to prevent this error coming up again and fix this
by special casing '.' in the new module_list to reduce the difference
between the old and new module_list.

This applies on v2.7.4
I looked at alternatives of how to fix it, e.g.
later in module_list to make an exception for calling
if (ps_matched && report_path_error(ps_matched, pathspec, prefix))
result = -1;
but that is similarly ugly.
