[PATCH 3/3] libplacebo: add forward compatibility with libplacebo v4+

From: Niklas Haas <[email protected]>

Current libplacebo git master has dropped fields deprecated in
libplacebo v2, but we remain backwards compatible with libplacebo v2 due
to reasons of debian stable / ubuntu LTS.

Rather than bumping up to libplacebo v3 (which would allow us to drop
these deprecated functions entirely), simply add forward compatibility
defines for now. Can be removed whenever there's a new ubuntu/debian
release.
