sparc: Make SA_NOMASK a synonym of SA_NODEFER

Unlike other architectures, sparc currently has no SA_NODEFER
definition but only the older SA_NOMASK. Since SA_NOMASK is the
historical name for SA_NODEFER, add SA_NODEFER and copy what other
architectures do by making SA_NOMASK a synonym for SA_NODEFER.
