When a sysadmin wishes to monitor module unloading with a syscall rule such as:
-a always,exit -F arch=x86_64 -S delete_module -F key=mod-unload
the SYSCALL record doesn't tell us what module was requested for unloading.
Use the new KERN_MODULE auxiliary record to record it.
The SYSCALL record result code will list the return code.

Jessica? If there are no objections to this patch on your side I'll
merge this into the audit/next tree.
Looks good to me:
