Include builder_name in full_results in telemetry_unittests.

Include builder_name in full_results in telemetry_unittests.

Turns out we need it to be included in full_results.json as
well as passed as a URL parameter :(.

Incidentally, down the road we should include all the things in the json, e.g.
step name, master url, etc. Sometimes when reading these files out you want to
know these things, but don't have the query parameters.

Oh, hey, I actually had this one documented as being needed, and missed it
anyway :(.

I think the only two other fields that are URL parameters but aren't included
are the step name / test type and the master name. It's certainly easy enough to
include them.

We could also add things like platform, configuration, etc., if you didn't want
to have to derive that from the builder name.

Yup. I want all these things. It's really silly that we try to derive that from
the builder name, especially since the builder name sometimes doesn't have all
that information.
