    fetch/gitsm: avoid live submodule fetching during unpack()
    
    Although the submodules' histories have been fetched during the
    do_fetch() phase, the mechanics used to clone the workdir copy
    of the repo haven't been transferring the actual .git/modules
    directory from the repo fetched into downloads/ during the
    fetch task.
    
    Fix that, and for good measure also explicitly tell Git to avoid
    hitting the network during do_unpack() of the submodules.
