ISO tracker URLs slightly messed up for trusty, be creative

[Adam Conrad]

As Nick pointed out[1], we're in the process of testing the 14.04.1
ISOs.  It's been noted that the tracker is producing broken URLs to
download those images.  If you just insert "trusty/" before the bit
with "daily" or "dvd", it should work fine.

For example:

http://cdimage.ubuntu.com/edubuntu/dvd/20140722.1/trusty-dvd-amd64.iso

Becomes:

http://cdimage.ubuntu.com/edubuntu/trusty/dvd/20140722.1/trusty-dvd-amd64.iso

Happy testing.
