[OE-core] [PATCH 3/3] sstate.bbclass: brute force silence fetch errors

[Christopher Larson]

From: Christopher Larson <chris_larson at mentor.com>

bb.fetch2.Fetcher.download() prints any fetch errors that come from the
underlying fetcher, rather than letting the caller do so, which means there's
no way to silence the fetch error messages without manipulating the loggers.
So we do so. The reason for doing this is that the user doesn't care if we
failed to fetch an sstate archive, the failure mode is just to rerun the real
task anyway.
