QCocoaDrag: don't add pasteboard items with non-absolute URLs

Browse Source 
AppKit rejects them and we end up with inconsistent number of pasteboard
items and drag images:

"NSURLs written to the pasteboard via NSPasteboardWriting must be absolute URLs."
"There are 1 items on the pasteboard, but 2 drag images."

Fixes: QTBUG-105711
