meson: Add a "python" option to make the python to build against configurable

This allows us to build with Python 2 and run tests with it.
This requires the new "python" meson module which was added in 0.46.0 so
bump the required meson version (glib needs a newer one anyway).

Also fixes a small test error under Python 2.
