  [Linux] Prevent encoding of DMABufObject lvalue references
https://bugs.webkit.org/show_bug.cgi?id=248395

Reviewed by Michael Catanzaro.

Remove the lvaue-ref-qualified DMABufObject::encode() method, only leaving
the encoding possible for rvalues of this type. Currently this method is
not used, so everything continues to work. But in any future encoding of
such objects, rvalues will be demanded, avoiding accidentally duplicating
the underlying resources (specifically the different file descriptors).

(WebCore::DMABufObject::encode const): Deleted.
