Jacob Keller d10e3b4260 submodule: don't pass empty string arguments to submodule--helper clone ...

When --reference or --depth are unused, the current git-submodule.sh
results in empty "" arguments appended to the end of the argv array
inside git submodule--helper clone. This is not caught because the argc
count is not checked today.

Fix git-submodule.sh to only pass an argument when --reference or
--depth are used, preventing the addition of two empty string arguments
on the tail of the argv array.
