audit: Add cmd helper for processing audit options
osi_audit_cmd_Options will handle the processing for the
-audit-interface and -audit-log command line options.
The auditlog / audit-interface options are used by several services;
this new helper routine provides a simple method to process the audit
related command line options in a consistent fashion.
