audit: log module name on delete_module

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.
