Change default program for all hooks from /bin/true to true.

At least on Mac OS, true is /usr/bin/true, not /bin/true. So the old default
/bin/true causes all hooks to fail on these systems. Since we execute external
programs via execvp() anyway, there is no need to hardcode the path.

Thanks to Henry Vogt for pointing out this flaw.
