rpm: produce sane amount of logging when creating a rootfs

Previously there was lots of irrelevant noise in the logs,
because we also wanted to be able to debug postinst issues
easily. I have adjusted the logging levels so that
postinst info is still written to the logs, but other
things are not.

+That way we can debug scriptlet failures without writing lots of
