Subject: [PATCH v7 4/7] perf config: Use combined {fore,back}ground colors value instead of each two color

To easily set default config values into actual variables for 'colors' config,
it would be better that actual variables for each 'colors' config
have only one value like 'default_config_item' type.

If we use combined {fore,back}ground colors values in ui_browser_colorset,
it smoothly work to initialize default config values for 'colors' config
by 'colors_config_items' array that contains default values for it at util/config.c.
because both actual variable and config item of 'colors_config_items'
are equal in the number of values (as just one).
