Bug 23720: Add div wrapper to search results to make moving cover images easier

TEST PLAN:

1. Apply this patch and turn on some cover images.
2. Add this CSS: '.bibliocol {display: flex;}.coverimages
   {padding-right:20px;}' to the OPACUserCSS.
3. Notice covers on left.
4. Remove CSS and notice covers should look normal on the right side.
