filter-branch: use require_clean_work_tree
Filter-branch already requires that we have a clean work
tree before starting. However, it failed to refresh the
index before checking, which means it could be wrong in the
case of stat-dirtiness.
Instead of simply adding a call to refresh the index, let's
switch to using the require_clean_work_tree function
provided by git-sh-setup. It does exactly what we want, and
with fewer lines of code and more specific output messages.
