QWaylandMimeData: Skip "DELETE" format
This is presumably a left-over from XDND:
https://freedesktop.org/wiki/Specifications/XDND/
> In general, XdndActionMove is implemented by first requesting the data
> and then the special target DELETE defined in the X Selection
> protocol. [...] DELETE should be sent before XdndFinished.
Firefox sends this during dragging of files but trying to fetch it
will fail, leading to a timeout and potential freeze.
Pick-to: 6.7 6.6 6.5
