[PATCH ghak120] audit: trigger accompanying records when no rules present

[Richard Guy Briggs]

When there are no audit rules registered, mandatory records (config,
etc.) are missing their accompanying records (syscall, proctitle, etc.).

This is due to audit context dummy set on syscall entry based on absence
of rules that signals that no other records are to be printed.

Clear the dummy bit in auditsc_set_stamp() when the first record of an
event is generated.
