[PATCH 02/10] git-submodule.sh: dispatch "sync" to helper

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Remove the cmd_sync() wrapper for "git submodule--helper sync" in
favor of dispatching the raw command-line directly to the helper.

At this point we've already parsed out the optional "--quiet" flag
that we need to support for "git submodule --quiet" (as opposed to
"git submodule <subcommand> --quiet").

This changes the output we'll display on invalid usage for the better,
before this we'd emit e.g.:

	$ git submodule sync --blah
	usage: git submodule [--quiet] [--cached]
	   or: [...many lines of "or" usage omitted...]

But now we'll emit the much more useful:

	$ git submodule sync --blah
	error: unknown option `blah'
	usage: git submodule sync [--quiet] [--recursive] [<path>]

	    -q, --quiet           suppress output of synchronizing submodule url
	    --recursive           recurse into nested submodules

This is because we'll now get as far as module_sync()'s failing call
to parse_options() when we have invalid usage.
