bitbake: fetch2/gitsm.py: Fix the references when the module and path are different

Git does not require the module and target path to be the same in the
.gitmodules file.  This incorrect assumption was being made previously
causing various unpack failures.

An example .gitmodule showing this issue:

   [submodule "plugins/WaveShaper/Libs/inih"]
        path = plugins/wolf-shaper/Libs/inih
        url = https://github.com/pdesaulniers/inih.git

The unpack function also needed to work in a loop on the overall
submodules_queue.  Before it could have missed items that were not in the
primary repository.
