Subject: [PATCH ghau40 v2 1/5] AUDIT_CONTAINER message type basic support

This defines the message number for the container ID registration record
should the kernel headers not be up to date, gives the record number a
name for printing and allows the record to be interpreted since it is in
the 1000 range like AUDIT_LOGIN.
