Reference pbench_install_dir enviroment variable

We reference the `pbench_install_dir` environment variable instead of
fetching it from the config file directly since `base` provides it.

We also fix a few tabs vs spaces issues, and add the "item" which was
in error when looping through the list of sysinfo items to execute.
