[PATCH] make set_loginuid obey audit_enabled

Hi, I was doing some testing and noticed that when the audit system was disabled, I was still getting messages about the loginuid being set. The following patch makes audit_set_loginuid look at in_syscall to determine if it should create an audit event. The loginuid will continue to be set as long as there is a context.
