Compute separator color against correct background color.

The existing code was mistakenly still using the text color when I'd intended to
change it to the background color.  Fix that.

Along the way, I discovered that the omnibox theme uses different background
colors than our spec claims.  Adjusted the alpha value slightly based on this.
As a result of the different background colors and the new alpha, the actual
contrast ratios of this patch are normal = 2.44, incognito = 3.67, which is
nearly-identical to the originally-landed-in-2016 design's 2.44/3.69.
