Remove an error importing shiboken
Remove an error importing shiboken

A long standing error was in qstandarditemmodel_test.py when shiboken2 was
not found. This is due to quite weird path settings with are generated by ctest.

With an adapted path setting, this now works, and we can again remove
qstandarditemmodel_test.py from the blacklist.
