t4015: prefer --color to -c color.diff=always

Browse Source 
t4015 contains many color-related tests which need to
override the "is stdout a tty" check. They do so by setting
the color.diff config, but we can accomplish the same with
the --color option. Besides being shorter to type, switching
will prepare us for upcoming changes to "always" when see it
in config.
