Add a web-platform reftest multicol-breaking-nobackground-004.html
For a better symmetry between the multicol-breaking tests and their no
background variants, this patch adds a nobackground test for
multicol-breaking-004.html. This tests the same things as
multicol-breaking-004.html, but with two things removed: outer column's
blue column-rules and inner columns' background.
