packager: TerminalReporter: stop reporting global cache errors

Summary: At FB we log errors into the error infra, and these errors are not actionnable for end users, so let's reduce the noise generated on the terminal. In the OSS case, people can simply add a handler in a TerminalReporter decorator, the same way we do internally (anyhow, I do not know of anyone using the global cache in OSS for now).
