Twenty Fifteen: input and textarea color

[afercia]

In the dark color scheme (maybe in the other ones too?), input fields of type text, email, search, etc., and textarea color have a couple of issues:

• text color is too light
• textarea color changes to #333 on focus, inputs color doesn't

See screenshot:

proposed patch removes affected elements selectors from "Secondary Text Color" in customizer.php, so they will use colors set in the main CSS, including #333 on focus.

Thanks for the report. This will be fixed when the patch when 29976.2.diff is committed. Ref: #29976.
