Fix auto-bisect presubmit so that it checks config files again.

Fix auto-bisect presubmit so that it checks config files again.

When I changed this PRESUBMIT.py in http://crrev.com/292434, I didn't properly test it, so it hasn't actually been checking auto_bisect/bisect.cfg as it was supposed to.

This change makes so that the files listed in the CONFIG_FILES list here will be checked (including run-perf-test.cfg, even though it's outside of the auto_bisect directory).
