[PATCH 07/14] bisect: add t6041 for submodule updates

[Jens Lehmann <Jens.Lehmann@web.de>]

Test that the bisect command updates the work tree as expected. To make
that work with the new submodule test framework a git_bisect helper
function is added. This adds a commit after the one given to be switched
to and makes that one the bad commit. The starting point is then given to
bisect as the good commit which makes bisect change the work tree to the
commit in between, which is the commit given.
