[PATCH] knotty: Don't show errors for universe provider issues

[Richard Purdie <richard.purdie@linuxfoundation.org>]

When running universe builds, we don't expect an error exit code for
provider warnings. Change the error messages to warnings in this case.

This deals with errors causing problems on our autobuilders amongst 
other issues.
