Correct query for formats supported by wxDataObject in wxGTK wxClipboard.

We wrongly asked wxDataObject for the formats it could provide on output
instead of those it accepted as input in wxClipboard::GetData() in wxGTK.
This could result in clipboard not working for "asymmetrical" data objects.

See #11811.
