wlr_scene: fix tf/prim comparison for scanout attempt

Browse source 
We were incorrectly doing comparison with `!= 0` to detect non-sRGB
tf/primaries. Since these enums are bit flags, the default sRGB values
are 1, not 0, so sRGB buffers were incorrectly rejected.

Fixes: bf40f396bf ("scene: grab image description from output state")
