bitbake: fetch2: improve error output for checksum failures
* Don't print the full exception in the initial warning - if we later succeed in fetching the file from a mirror, we won't usually need the details (which are in the fetch log if they are needed); otherwise the full error will be printed when the fetch operation fails. Also adjust the conditional block so that we don't print another warning just mentioning we're going to try mirrors. * Call logger.error() so that with knotty the full log is not printed * Provide an explanation around the lines we print for easily updating the checksums in the recipe. We don't want users to be just blindly updating the recipe in case of a transient failure or deliberately altered remote file.
