Allan McRae 82abe079ab Point python shebangs at python2
Python PEP-394 states that all python code should point at the
python2 or python3 symlinks at maintain cross-distro compatibility.

Note that this does not matter when calling these scripts using
"make check" as they are explictly called using the detected python
version.  As this only affects manually calling these scripts, I
have not had configure/make replace the shebangs.
