modules/blinds: use til_fb_put_pixel_checked()
While testing an experimental checkers w/fill_module=blinds with ASAN it became clear this module is making flawed assumptions about fragment->frame_{width,height} and fragment->{width,height} being equal. When used by checkers for filling cells, there are situations where the edge cell fragments need to describe a frame slightly larger than the drawn area, because the cell size doesn't align perfectly to the overall window/screen dimensions. So in these cases the synthesized frame will still be a full cell's dimensions while the width,height serve to clip within that area. If modules aren't properly clipping their rendering, instead just using frame_{width,height}, then they will have to use the _checked() variants to ensure clipping occurs properly on a per-pixel (slower) basis.
