Make superuser the owner of registers from the kernel.

Registers from the kernel do not come in on AF_LOCAL sockets so the exact owners of the service can not be determined. But given the fact the loopback address is used and a privilege port used, it can be assumed the owner of the service should be the superuser. Signed-off-by: Steve Dickson <[email protected]>
