Update Python installation on Debian
Between Debian 11 and 12 the way to install Python packages into the
system location under /usr, and not /usr/local, changed[1]. The
previous setup argument --install-layout=deb is now unsupported and the
environment variable DEB_PYTHON_INSTALL_LAYOUT needs to be set instead.
See also [2].
