From: Emily Shaffer <emilyshaffer@xxxxxxxxxx>
Move the running of the 'post-checkout' hook away from run-command.h
to the new hook.h library in builtin/worktree.c. For this special case
we need a change to the hook API to teach it to run the hook from a
given directory.
We cannot skip the "absolute_path" flag and just check if "dir" is
specified as we'd then fail to find our hook in the new dir we'd
chdir() to. We currently don't have a use-case for running a hook not
in our "base" repository at a given absolute path, so let's have "dir"
imply absolute_path(find_hook(hook_name)).
