productivity/tryton: add cdn to MASTER_SITES

Hi,

tryton upstream added a cdn in front of their downloads.tryton.org host
to reduce the load for serving static files.

The following diff makes all tryton ports uses downloads-cdn.t.o first,
and next fallback to downloads.t.o.

I assume changing MASTER_SITES doesn't require to bump REVISION.

I checked that the tarballs are the same (make fetch doesn't complain
about change in hashes).

Comments or OK ?
