Subject: Add PYTHON_INSTALL_EXTRA_OPTIONS and --install-layout=deb


Debian packages should be installed under dist-packages, not
site-packages. Debian has patched distutils and setuptools to add a new
flag '--install-layout'. For --with-ipaplatform=debian,
PYTHON_INSTALL_EXTRA_OPTIONS is set to '--install-layout=deb'.
