cmake: update interpreter requirement for the test suite generator
The test suite generator has been a Python script for a long time,
but tests/CMakeLists.txt still looked for Perl. The reference to
PYTHON_INTERP only worked due to a call to find_package(PythonInterp)
in the toplevel CMakeLists.txt, and cmake would not have printed the
expected error message if python was not available.
