submodule update: remove -v, pass --quiet

In cmd_update(), "-v" unsets GIT_QUIET, but this does nothing because
GIT_QUIET is only set when "-q|--quiet" is passed.

Remove "-v", and since "git submodule--helper update" already
understands 'quiet' options, append them to `opts`. This makes GIT_QUIET
obsolete, so remove it.
