contrib: Improve dg-extract-results.sh's Python detection [PR109668]

Browse Source 
'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.
