color.c: alias RGB colors 8-15 to aixterm colors
This results in shorter output, and is _probably_ more portable. There
is at least one environment (GitHub Actions) which supports 16-color
mode but not 256-color mode. It's possible there are environments
which go the other way, but it seems unlikely.
