Revise hcsecd(8) and sdpd(8) rc.d scripts.

- Have both scripts automatically kldload ng_btsocket(4). I did not want to
  do it, but its easier for users and it seems other scripts do similar things;

- Assign few variables after load_rc_config, so the /etc/rc.conf overrides
  actually work;

MFC after:	1 week
