Fix background and foreground color of font in controls in web page

OzoneWebUI is a sub class of LinuxUI that provides several methods
to get toolkit theme colors, but Weston doesn't provide any theme
for widget drawing. So we use default color values set by Content
Shell and ChromeOS:
content/public/common/renderer_preferences.cc
chrome/browser/renderer_preferences_util.cc
