support/scripts/graph-depends: use colors instead of colours

The graph-depends was not very consistent in colors vs. colours: some
parts were using colours, some parts were using colors.

Let's settle on the US spelling, colors.

This change the user-visble option --colours to --colors, but it is
unlikely that a lot of users customize the colors through
BR2_GRAPH_DEPS_OPTS, so this user interface change is considered
reasonable.
