Fix test generation on Arch Linux.
On Arch Linux, "python" means Python 3.x, and Python 2.x is called
"python2". The test generation code requires Python 2.x. In many
other distributions, "python" refers to Python 2.x.
This patch adds logic to the toplevel CMakeLists that checks both
"python2" and "python" to see which one is Python 2.x, and once it is
found, sets the cmake variable ${python} to point to it.
