Fix border size computation in wxAuiTabArt.

Space was reserved for the borders even when it wasn't filled, resulting in
visual artefacts. Fix this by virtualizing the function returning the
additional space needed for the borders and only overriding it to return non
zero in wxAuiGtkTabArt.

Closes #14710.
