submodule--helper update-clone: learn --init
Teach "git submodule--helper update-clone" the --init flag and remove
the corresponding shell code.
When the `--init` flag is passed to the subcommand, we do not spawn a
new subprocess and call `submodule--helper init` on the submodule paths,
because the Git machinery is not able to pick up the configuration
changes introduced by that init call. So we instead run the
`init_submodule_cb()` callback over each submodule in the same process.
