Title: Make yumpkg module log locally to /var/log/yum.log

The addition of _YumErrorLogger effectively killed local yum logging.
This commit modifies the logger to behave more like
yum.rpmtrans.RPMBaseCallback, bringing back logging to /var/log/yum.log
while preserving the special error logging that this class initially was
written to provide.
