[PATCH RESEND 2/4] perf tools: Separate out code setting {back, fore}ground colors from ui_browser__color_config

[Taeung Song]

ui_browser__color_config() set foreground and background
colors values in ui_browser__colorsets.
But it can be reused by other functions so make ui_browser__config_colors()
bringing it from ui_browser__color_config().
