contrib: Improve dg-extract-results.sh's Python detection [PR109668]
'python' on some systems (e.g. SLES 15) might be Python 2. Prefer python3,
then python, then python2 (as the script still tries to work there).
PR other/109668
* dg-extract-results.sh: Check for python3 before python. Check for
python2 last.
(cherry picked from commit 64273a7e6bd8ba60058174d147521dd65d705637)
