avfilter/vf_vibrance: Update default value of rlum/blum
Fix #9195
It looks like vf_vibrance.c is similar to
https://github.com/zachsaw/RenderScripts/blob/master/RenderScripts/ImageProcessingShaders/SweetFX/Vibrance.hlsl
and
https://github.com/kevinlekiller/kwin-effect-shaders_shaders/blob/main/Vibrance.frag
Originall written by Christian Cann Schuldt Jensen ~ CeeJay.dk.
They use same matrix coeff.
