Send SIGKILL to kill the child.

PostinstallRunnerActionTest.RunAsRootCancelPostinstallActionTest wasn't able
to kill the child in brilloemulator because it send a SIGTERM to the child
before the child exec, and the SIGTERM was ignored.
So we instead send a SIGKILL to kill the child which won't be ignored.

Test: adb -s emulator-5554 shell /data/nativetest/update_engine_unittests/update_engine_unittests
