[css-text] Fix test and update TestEpectations

The test word-break-break-all-inline-006.html is incorrectly defined, as
it was agreed in the corresponding CSS WG issue [1].

This CL changes the expected result of the test and updates the
TestExpectations accordingly, since it was failing for LayoutNG before.

The new expected result matches current LayoutNG's and Gecko's behavior,
but it implies that it fails in legacy and WebKit.

+Some browsers may decide to break before the last 'b', which is still conformant from the spec
+perspective. However, this test would fail in that case. Current spec states that behavior is
+undefined in the boundaries of the inline-box. See https://github.com/web-platform-tests/wpt/issues/19903
