t/jsonplus2csv_test.py: test script for tools/fio_jsonplus_clat2csv

Add a script to run a basic jsonplus to CSV conversion and then validate
the conversion.

Also integrate this test script with t/run-fio-tests.py and install the
python package 'six' to support fio_jsonplus_clat2csv in the AppVeyor
build/testing environment.
