libtuning: agc: rkisp1: Increase y-target
With the addition of gamma out correction the relative luminance target was set too low. As brightness is a bit subjective it is difficult to come up with the "correct" value. With 0.5 the patch 22 on the macbeth chart (neutral grey, 18% reflectance) ended up a bit below 50% grey, which seems reasonable.
