perf diff: Color the Ratio column
In $ perf diff -c ratio color the Ratio column using value_color_snprintf(), a new function that operates exactly like percent_color_snprintf(). At first glance, it looks like percent_color_snprintf() can be turned into a non-variadic function simplifying things; however, 53805ec (perf tools: Remove cast of non-variadic function to variadic, 2013-10-31) explains why it needs to be a variadic function.
