capabilities: remove all _real_ interfaces
The name security_real_capable and security_real_capable_noaudit just don't make much sense to me. Convert them to use security_capable and security_capable_noaudit. Signed-off-by: Eric Paris <eparis@redhat.com> Acked-by: Serge E. Hallyn <serge.hallyn@canonical.com>
