Use same python version in ReduceSCD_Parallel

Description

On topaz.sns.gov there are two versions of python: 2.6 and 2.7. 2.7 is the default. Since mantid is compiled with 2.6 this is a problem. If one directly uses python2.6 to start ReduceSCD_Parallel.py (as they should) the inner script that is run for a single run uses the default python. The fix is to use sys.executable rather than python on line 90. Unfortunately that can return None so trap for this and use the default python instead of failing.

To test: just review the code on ​bugfix/7920_reduce_scd_parallel and try to run the script. Tara is probably the best tester at this point.

Tested by running parallel reduction on topaz2 using this script with python2.6 and it works now.
