Don't attempt to use chroot() on systems that don't support it.

This has the added bonus of allowing us to use popen() rather than
fork()/exec() for improved portability. Of course, the loss of an
install root is a major reduction of functionality but it's hard to
see what else we could substitute for chroot().
