Subject: [PATCH] fetchtorrent: test using Sintel torrent

The current torrent used for testing fetchtorrent isn't free, which
prevents the tests running in a lot of environments.  Swap for a torrent
of the Sintel film, which has a free license.

This unfortunately increases the closure size of the tests: Sintel is
124MB, compared to 54MB for the Wired CD.  This was the smallest torrent
I could find that both had a free license and was sufficiently well
seeded to be useful for testing.
