[PATCH 1/5] fbconsole: use symbolic names for ANSI colors

[Ahmad Fatoum <a.fatoum@barebox.org>]

Instead of hardcoding color indices, let's define symbolic names and use
them throughout. This makes it clear that we are using different default
colors, which will be fixed in the follow-up commit.

No functional change.
