submodules: ensure clean environment when operating in a submodule
git-submodule used to take care of clearing GIT_DIR whenever it operated
on a submodule index or configuration, but forgot to unset GIT_WORK_TREE
or other repo-local variables. This would lead to failures e.g. when
GIT_WORK_TREE was set.
This only happened in very unusual contexts such as operating on the
main worktree from outside of it, but since "git-gui: set GIT_DIR and
GIT_WORK_TREE after setup" (a9fa11fe5bd5978bb) such failures could also
be provoked by invoking an external tool such as "git submodule update"
from the Git Gui in a standard setup.
Solve by using the newly introduced clear_local_git_env() shell function
to ensure that all repo-local environment variables are unset.
