Branched internal RuntimeCost in junitrunner.

RuntimeCost class is needed by the package com.google.testing.junit.runner.sharding.weighted. I branched it from the internal code because the weighted package is now open sourced and does not have access to the previous import. 

This didn't break Bazel before because there was no dependency to the weighted target when building BazelTestRunner. I catched this trying to open-source junitrunner tests.
