Frantisek Hrbata 3dd24c70fc fix(test_submodules.py): don't rely on submodule init
Current version of the test is using "git-submodule foreach", which
requires submodules to be initialized. Non-initialized submodules are
ignored. Our CI is not performing submodule initialization, but instead
it only downloads the submodule content in tools/ci/ci_fetch_submodule.py
from cache and copies it into the submodule path.

Since we already know the submodule path from .gitconfig, we can use it
as argument to git-ls-tree and avoid calling git-submodule at all. This
allows to perform the test even if the submodules are not initialization
and also it makes the code simpler.
