Subject: [PATCH] refpolicy: fix optional issue on sysadm module
init and locallogin modules have a depend for sysadm module because
they have called sysadm interfaces(sysadm_shell_domtrans). Since
sysadm is not a core module, we could make the sysadm_shell_domtrans
calls optionally by optional_policy.
So, we could make the minimum policy without sysadm module.
