Define travis matrix in .sync.yml

Since the other modules need to wait for a major release before
deprecating Puppet 2.7 support, this module's travis.yml is out of sync
and will need to stay that way for a while.

Add json gem

The puppet_facts gem implicitly depends on the json gem.
On Ruby 1.8.7, json is not built in. On Puppet 2.7, it is
not explicitly pulled in by the hiera gem. So we add it
here explicitly.

Pin backports to 'release' instead of 'origin'

This allows backports to reside on the same origin, e.g. http.debian.net, without setting the pin priority to 200 for all repositories on http.debian.net.
Update backports related tests
