Have setup_benchmark_data_and_tables.sh go through the tpchgen-cli install path

Right now setup_benchmark_data_and_tables.sh will fail if we don't have tpchgen-cli installed, which is unlike the generate_dataset.sh path, which installs tpchgen-cli first and then generates data.

Both use the underlying generate_data_files.py script, so they should include the same wrapper steps to get there.
