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.
