[U-Boot] [PATCH 3/4] buildman: Rename the good, better, worse variables

[sjg at google.com]

At present we don't distinguish between errors and warnings when printing
the architecture summary. Rename the variables to better describe their
purpose.

'Worse' at present means we got an error, so use that as the name.
