Update expected file for hyphens-auto-mock.html

Legacy does not use hyphenation points that are beyond the
line end, but LayoutNG does. The LayoutNG behavior is more
correct. This patch updates the expected file to the LayoutNG
behavior, and marks the test to fail in `disable-layout-ng`.

Note, while crbug.com/870219 was fixed in LayoutNG, the test
from the reporter still has a few undesired results, due to
crbug.com/1022415 (sometimes it hyphenates though, which is
unexpected) and crbug.com/1140738. By adding one more word and
using the build the latter issue was fixed, the result looks
correct.
