fix(Transport): Disable automatic User Agent Suffix [clone of #1420] (#1423)

CLONE OF #1420

This small fix to the Kotlin Transport code, disables automatic User
Agent suffixing by the Google-HTTP-Java library.

Looker is very specific about User Agent names, especially when using
cookieless embedding sessions and this change will fix the contract
violation between this code and the API.
