My first thought of a fix was just that, but I remembered that the
capabilities code is built regardless of the CONFIG_SECURITY setting
and I thought there might be some value in allowing for lsm_audit to
be used in commoncap (although in full disclosure commoncap doesn't
currently make use of lsm_audit).
