contrib/rerere-train: use installed git-sh-setup

gitster · gitster · commit 53876fcf3fdc · 2012-04-30T12:50:38.000-07:00
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.
