test: add regression test for lgpl-3.0_16 required phrases

Add a lic4 datadriven fixture with the LGPL-2-or-later notice header
from KDE libqzeitgeist src/logbrowser.cpp (issue #4995): it must detect
as lgpl-2.0-plus only and no longer match lgpl-3.0_16.RULE now that the
rule requires its GNU Lesser General Public License version 3 phrases.
