    wayland/data-device: Use correct selection type to get mime types
    
    When primary_offer_receive checks if the requested mime_type is supported,
    it should check against the list of mime-types supported by the
    primary-selection, instead of the list for the clipboard.
    
    This fixes primary selection copy paste from X11 apps to Wayland apps
    not working.
