The chpass Makefile tried to set the fschg flag on the binaries, even if NO_FSCHG was passed to the installworld. This meant that if I installed FreeBSD into a Jail, I couldn't installworld from within the Jail anymore. Now that it listens to NO_FSCHG, we can just make it bail out when it fails, just like PRECIOUSPROG does.
