builtin/checkout: add --recurse-submodules switch

Browse Source 
This exposes a flag to recurse into submodules
in builtin/checkout making use of the code implemented
in prior patches.

A new failure mode is introduced in the submodule
update library, as the directory/submodule conflict
is not solved in prior patches.
