SubjectRe: [PATCH 08/28] SECURITY: Allow kernel services to override LSM settings for task actions [try #2]

FYI, I added the following vectors:

# kernel services that need to override task security
class kernel_service
{
use_as_override
create_files_as
}

The first allows:

avc_has_perm(daemon_tsec->sid, nominated_sid,
SECCLASS_KERNEL_SERVICE,
KERNEL_SERVICE__USE_AS_OVERRIDE,
NULL);

And the second something like:

avc_has_perm(tsec->sid, inode->sid,
SECCLASS_KERNEL_SERVICE,
KERNEL_SERVICE__CREATE_FILES_AS,
NULL);

Rather than specifically dedicating them to the cache, I made them general.
