  VDPAU: Fix CSC matrix support detection

- we were testing for feature support but need to test attribute support
- which worked on NVIDIA hardware as it supports temporal spatial
deinterlacing; a feature that has the same enum value, whereas AMD
hardware does not support it and CSC detection failed (when it is
supported)
