st/vega: fix drawing images with alpha channel

Checking if the paints are opaque in renderer_validate_blend() does not
work.  We could be drawing images.  Remove the check from
renderer_validate_blend() and take image drawing into consideration in
blend_use_shader().

The bug was introduced by 3f0a966807f03a364edea0272ddf45f08ab7ce4f,
which affects the lookup demo.
