packaging: drop tests & tests data from the Python package

[ogayot]

When building the debian package, dh_missing complains that files in probert/rtnetlink/tests are not installed. We could add them to debian/not-installed but really we don't want them in the package at all. Drop them along with other existing test modules.

^ This is required for building console-conf with recent probert.

dh_missing: error: missing files, aborting

	While detecting missing files, dh_missing noted some files with a similar name to those
	that were missing.  This error /might/ be resolved by replacing references to the
	missing files with the similarly named ones that dh_missing found - assuming the content
	is identical.

	As an example, you might want to replace:
	 * debian/tmp/usr/lib/python3.13/dist-packages/probert/rtnetlink/__init__.py
	with:
	 * usr/lib/python3.13/dist-packages/probert/tests/rtnetlink/__init__.py
	in a file in debian/ or as argument to one of the dh_* tools called from debian/rules.
	(Note it is possible the paths are not used verbatim but instead directories 
	containing or globs matching them are used instead)

	Alternatively, add the missing file to debian/not-installed if it cannot and should not
	be used.

	The following debhelper tools have reported what they installed (with files per package)
	 * dh_install: probert (0), probert-common (28), probert-firmware (1), probert-network (8), probert-storage (12)
	 * dh_installdocs: probert (1), probert-common (0), probert-firmware (0), probert-network (0), probert-storage (0)
	If the missing files are installed by another tool, please file a bug against it.
	When filing the report, if the tool is not part of debhelper itself, please reference the
	"Logging helpers and dh_missing" section from the "PROGRAMMING" guide for debhelper (10.6.3+).
	  (in the debhelper package: /usr/share/doc/debhelper/PROGRAMMING.md.gz)
	Be sure to test with dpkg-buildpackage -A/-B as the results may vary when only a subset is built
	If the omission is intentional or no other helper can take care of this consider adding the
	paths to debian/not-installed.
