Commit 10ecfa7649 (verify_path: disallow symlinks in .gitmodules,
2018-05-04) made it impossible to load a symlink .gitmodules file into
the index. However, there are no tests of this behavior. Let's make sure
this case is covered. We can easily reuse the test setup created by
the matching b7b1fca175 (fsck: complain when .gitmodules is a symlink,
2018-05-04).

This script has already expanded beyond its original intent of ".. in
submodule names" to include other malicious submodule bits. Let's update
the name and description to reflect that, as well as the fact that we'll
soon be adding similar tests for other dotfiles (.gitattributes, etc).
We'll also renumber it to move it out of the group of submodule-specific
tests.
