Package audit-config is created to config customized config
file of audit. Since there is no other change for audit,
we could replace srpm with rpm directly.
audit-config is set to depends on audit, so audit rpm will be
installed automatically.
Test:
Pass build and multi node deploy test. Confirm syslog.conf is
the same as before in the deploy.
