No need to cd back before exiting a shell script that is run as a command

The autogen.sh script is not supposed to be sourced ("source
autogen.sh"), but run as a command ("./autogen.sh"). After all, it has
the executable bit set. Also, the function called "failed" in it does
an "exit" at the end. That would be a rather rude thing to do as soon
as something goes wrong if the script is sourced.
