Move bisect-perf-regression.py into auto_bisect directory.

The purpose of this is to continue gathering all the related code together, and to make it easier to run pylint/tests for the main module which still contains most of the code.

After doing this, pylint and the tests caught a couple of things -- one unused variable name, and after the script changed directory, some of the paths had to be modified as well.
