ci/lava: Fix colour definitions

All the foreground colours pass 1 to ANSI SGR, which sets bold. The
other arguments are either a colour from 30-37 (passed directly), or
38;5;nnn, where nnn is an extended RGB colour. It looks like most of the
definitions were cargo-culted from FG_RED, which correctly sets an
extended colour, because the arguments there were being parsed as
setting blinking, followed by 197 which was ignored as unknown.

Fix them to just set the original definition.
