We may end up wrapping inside anonymous ruby base because while the base
has 'white-space:nowrap' the content doesn't necessarily have it.

* LayoutTests/fast/ruby/implicit-base-child-nowrap-expected.html: Added.

(ruby > rt):
(ruby > :not(rb, rbc)):

Set nowrap for any direct ruby children (except for unsupported ruby elements to avoid behavior changes for them).
