[roll] Roll antlion [runner] Forward termination signals to Python

Fix an issue where test timeouts in infrastructure resulted in no logs
uploaded to LUCI artifacts. This was caused by SIGTERM not being
forwarded to the Python process running antlion, communicating to the
Swarming bot that the test is unresponsive, resulting in a forced kill
before antlion-runner is able to run teardown() on the InfraDriver.
Since teardown wasn't being called, symlinks weren't being removed from
the output directory causing errors while uploading to CAS.
