git-submodule: replace duplicated code with a module_list function

Browse Source 
Several call sites in git-submodule.sh used the same idiom for getting
submodule information:

	git ls-files --stage -- "$@" | grep '^160000 '

This patch removes this duplication by introducing a module_list function.
