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.
