mac: Fix a bookmark bar unit test on OSX 10.10.

The test LastBookmarkResizeBehavior implicitly relied on the default system
font. The system font changed from 10.9 to 10.10, breaking the test. I updated
the test to use a different set of parameters on OSX 10.10+.

Which test does this fix, specifically? LastBookmarkResizeBehavior? If so, would
it be possible to just update the test without forcing the font? 10.10+
presumably will all use Helvetica Neue, so it'd be better if the test could
adapt more easily between the two font types. It looks like the test is just
trying to ensure that the off-the-side button is shown/hidden appropriately.
That should be testable on both platforms without this.

rsesek: Good suggestion, thanks! PTAL

I also updated the CL description to include the name of the test being fixed.
