Blacklist tst_QItemDelegate::comboBox on openSUSE

This failed (occasionally) in finding the editor widget, so wait for the window
to be shown properly. Also enter the event loop with QTRY_VERIFY and not for a
fixed time of 1 s.

This however just moved the point of failure. Now the test fails since the
clearing and setting of focus does not dismiss the editor widget sometimes, so
still blacklist it.
