Fix datafile path in datasources to contain "gp"

Although the fixed datasources are currently in use, we cannot remove
them until the scripts to generate grants are fully
understood. Therefore, we at least fix the path of the datafiles, they
use.

Removing script to add "gp" to paths in datasources

The script unconditionally adds "gp" to all datafile paths, regardless
of whether it already contains "gp" or not. So to avoid harm, we
remove the script, as we previously fixed all datafile paths by hand.
