[git-freeze] Ignore submodules when freezing.
It turns out we are already parsing the full output of `git status`,
so we may as well use that. This output already ignores submodules.
This also updates the freeze implementation to avoid unnecessary
calls to `git commit` when we already know if they are needed or
not.
Note that `git stash` (which `git freeze` is emulating) already
ignores submodules as well.
Ignoring submodules while freezing should make `git rebase-update`
work again inside of repos which have dirty submodules.
