Use "http://chromegw/i/tryserver.chromiumos/" for retrieving builder info.

This "/i/" url is the internal version of
"http://chromegw/p/tryserver.chromiumos/". And "/i/" links offer
waterfall controls (force build, stop build, etc.) and work for both
internal and public waterfalls, whereas "/p/" links only work for
public waterfalls.

BUG=None
TEST=buildbot_json.py works well with this url.
