Revert "vo_dmabuf_wayland: drop support for linux-dmabuf-v2"

Browse Source 
This was originally dropped because it was thought to be unneeded at the
time, but at least some devices (rockchip) apparently are still on old
compositors that use linux-dmabuf v2. It's not much code, and for
testing purposes it's good to have around since it's hard to test
drmprime otherwise. Some minor additions are here to support the newly
added vaapi-format mapping in v2 of the protocol.

This reverts commit a5b9d529ee.
