Carousel: Fix image styling in no-js format

[Scotchester]

Prior to this change, the item-visual-wrapper was adding some space under the image.

Tested this in Chrome, Firefox 44 (with #5974) and IE 11 and emulated 9. All behave as desired.

Changes

• Carousel item visual wrapper's display changed from inline-block to block

What're the steps to see the before state? I tried disabling JS on the live site in Chrome and Safari and I don't see a gap.

I guess Webkit has fixed the issue, but you can verify by disabling JavaScript in Firefox or visiting with IE 9.
