[PATCH] checkout: respect diff.ignoreSubmodules setting

<alpine.DEB.1.00.1008251225200.4020@intel-tinevez-2-302>

When 'git checkout' reports uncommitted changes, it also does so for submodules.

The default mode is now to look really hard into submodules, not only for different commits, but also for modified files. Since this can be pretty expensive when there are a lot (and large) submodules, there is the diff.ignoreSubmodules option.

Let's respect that setting when 'git checkout' reports the uncommitted changes, since it does nothing else than a 'git diff --name-status'.
