Fix #67325 : imagetruecolortopalette: white is duplicated in palette

gdImageTrueColorToPalette() is sometimes wasteful by putting multiple white
color entries into the palette. This is caused by an obvious typo, where
to avoid a division by zero when `total` is zero, `count` is checked instead
of `total`.

We fix this issue to improve the quality of the color quantization.
