[Orgmode] Slight fix to update-org.sh

[Tom Breton (Tehom)]

While updating to 6.22b, I remembered this:

I like pete's update-org.sh.  It's convenient when you haven't got git
(I'll get around to getting git someday, but it's not high priority)

It had a bit of a problem because my org directory wasn't a subdirectory
of my build directory.  I made some minor changes to make it do that and
to gunzip the archive.  I've attached it to this message.
