submodule: add get_submodule_config helper funtion
Several submodule configuration variables (e.g. fetchRecurseSubmodules) are read from .gitmodules with local overrides from the usual git config files. This shell function mimics that logic to help initialize configuration variables in git-submodule.sh. Signed-off-by: W.
