linux-dmabuf: send deprecated format events

Browse source 
Although the format event is deprecated, some clients, especially the
GStreamer waylandsink, only support zwp_linux_dmabuf_v1 version 1 and
require the deprecated format event.

Send format events instead of the modifier event, if the client binds on
a protocol version before version 3, skipping formats that only support
non-linear modifiers.
