By default generate-version-script.py uses /usr/bin/python3, whatever
version that may be - which causes problems if the default python3
installation is one either built without XML support or not included
in PYTHON_TARGETS of dev-python/setuptools. Make sure the script is
invoked using the same interpreter as meson itself, as that one is
already guaranteed to provide both 'xml' and 'pkg_resources'.
