We do already build the Git tools when building the test target (as
opposed to just libgit.a when building the cgit binary), but I can't
remember why we do this...

It's probably simplest just to further tweak $PATH in tests/setup.sh so
it also prepends "$(pwd)/../../git/bin-wrappers".  That should cause us
to use the Git tools from the submodule without needing to do anything
else.
