Add an option to disable expat
This patch replaces the existing --with-system-expat option with a
--with-expat={system,builtin,none} option, which allows to tell Python
whether we want to use the system expat (already installed), the expat
builtin the Python sources, or no expat at all (which disables the
installation of XML modules).
