Drop support for old compositors that don't use DmaBufs the way they are
supposed to be used now. There is now a whole negotiation process that
includes DmaBuf modifiers and there is also support for renegotiation in
case we fail to import DmaBufs with certain modifier. This is something
that didn't exist before and in such case, failing to import DmaBufs we
would just end up with broken screen sharing. For that reason it would
be better to use MemFD instead to make sure old compositors will work
just fine
