Subject: tdf#92903 KDE4: fix listbox regression from 92115

So at least in case of the CTRL_LISTBOX, getNativeControlRegion is
called for a type and part unsupported by IsNativeControlSupported.

For whatever reason, this results in broken listboxes drawn in
Base's "Table Design" dialog, when selecting "field type", which
draws the listbox on top of the cell.

To make it worse, it seems the listbox is actually drawn to a
smaller space then the actual requirement. Appearently it seems to
use the content rect, instead of the bounding rect.

So in addition to fixing the drawing, this patch increases the
listbox bounding rect, which looks too large in normal dialogs, but
makes the Base's listbox better readable.
