Adjust tst_qdbusmarshall to QVariant changes

Comparing QVariant's containing QDBusArguments does not work anymore in
Qt 6, where QVariant will simply use QMetaType equals. Thus we now do
the comparisons in a more manual way. This is currently only partially
implemented.
Additionally, adjust to changed warning message.

Fixes: QTBUG-87998
