Stefan Beller 3290fe6dd2 lib-submodule-update.sh: reduce use of subshell by using "git -C" ...

We write

    (cd <dir> && git <cmd>)

to avoid

    cd <dir> && git <cmd> && cd ..

that allows a breakage in one part of the test script to leave the
entire test process in an unexpected place.  Modern version of Git
allows us to do this more concisely with "git -C <dir> <cmd>".
