calipso: Allow the lsm to label the skbuff directly.
In some cases, the lsm needs to add the label to the skbuff directly. A NF_INET_LOCAL_OUT IPv6 hook is added to selinux to match the IPv4 behaviour. This allows selinux to label the skbuffs that it requires. Signed-off-by: Huw Davies <huw@codeweavers.com> Signed-off-by: Paul Moore <paul@paul-moore.com>
