auto-tools files update

We've just had a submission adding DragonflyBSD support to the code.

The contributor notes that the config.sub and config.guess files
distributed with Squid are outdated and need to be upgraded for the new
OS support to work.

Anyone know how/what is needed to be done to the bootstrap system to get
them into the source? Is it worth doing?
