Outliner: Don't draw library overrides indicator for override buttons

All the buttons in the Library Overrides display mode would be shown in cyan,
indicating that they are library overrides. Given that this is solely what this
display mode is about, the indicator is just redundant, confusing (why are the
buttons purple?) and looks weird.

Part of T95802.
