#996: Fix python_setup/install_tool.sh

When the script  executed on a runner which does not have python2, script incorrectly execute the code inside the if condition. This script runs using /bin/sh in Ubuntu and cause the problem. Fix for this issue to use different syntax in output redirection.

Issue is reproduced using running the job on ubunutu container. Fix also verified in the action https://github.com/cdivitotawela/codeql-issue/actions/runs/2038007502
