submodules: introduce check to see whether to touch a submodule
In later patches we introduce the --recurse-submodule flag for commands
that modify the working directory, e.g. git-checkout.
It is potentially expensive to check if a submodule needs an update,
because a common theme to interact with submodules is to spawn a child
process for each interaction.
So let's introduce a function that checks if a submodule needs
to be checked for an update before attempting the update.
