Mac: Non-editable QComboBoxes shouldn't get focus by default

On Mac, only line edits and list views always get tab focus. It's only
when we enable full keyboard access that other controls can get tab
focus. When it's not editable, a combobox looks like a button, and it
behaves as such in this respect.
