Bug 1506567 [wpt PR 14021] - Set orphans and widows to 1 in new multicol test., a=testonly

Automatic update from web-platform-testsSet orphans and widows to 1 in new multicol test.

The test left orphans / widows at their initial value (2), but did
assume that we could freely break wherever we wanted. Blink honors
orphans and widows requirements inside multicol containers, so set
them to 1, to get the behavior that the test expects.
