If the attempt to load the guest executable fails, print the error message as a string, not a number. This requires us to fix a couple of places in loader_exec() where we were returning -1 instead of a valid negative errno. The change allows us to drop the "Unknown binary format" message because the strerror-enhanced message is now a more self-explanatory "Error while loading $guest-binary: Exec format error".
