LibWeb: Don't infer SVG viewBox if width and/or height is zero

Browse source 
The fix here has two parts:
1. Don't use the fallback viewBox at all if we're not in SVG-as-image.
2. Don't make a fallback viewBox with zero width and/or height.

This fixes a crash on Bandcamp pages. Thanks Tim Flynn for reporting!
