[PATCH] contrib/rerere-train: use installed git-sh-setup

Instead of sourcing git-sh-setup from random place that is on the $PATH,
explicitly source $(git --exec-path)/git-sh-setup.  As I do not personally
have any libexec/git-core directory on my $PATH like many other people, the
script will fail without this update.

 * I recently was helped greatly by this old script written in Sept 2008.
   We may want to integrate it to "git rerere" proper some day, but that
   is a separate topic.
