[FIX] packaging: fix lxml.html.clean split

Since lxml.html.clean was moved to a separate package starting in lxml
5.2 the odoo Debian package was broken in Ubuntu 24.04.

A first fix was attempted in 318df32. While the package was properly
built with this fix and was installable, but Odoo failed to start under
Ubuntu. The bug flew under the radar because the simple test after the
package build is done with a Docker based on Debian Bookworm.

In fact, the fix was not taken into account because the python packages
defined in the debian/control are not really taken into account by
dh_python3 that tries to compute the python dependencies.

With this commit, a py3dist-overrides file is used to overrides the
package mapping between python packages and debian packages. The same
pipe trick is used as in the previous fix to ensure that the package is
installable in Ubuntu 24.04 (which provides python3-lxml-html) and in
Debian Bookworm (which does not provide the python3-lxm-html).

Finally, the Docker image used for the build and the test is changed to
use Ubuntu 24.04.
