Use Python 3 instead of Python 2 to generate test files
Python 2 is no longer officially supported, but we were still using it
to generate test suite .c files from .function files when using GNU
make. Switch to looking for Python 3.
CMake currently uses a system-dependent version of the Python language.
This commit does not affect CMake builds.
