Subject: hostapd: Allow rsn_preauth configuration

Hostapd can allow preauthentication for WPA2-EAP networks when
the interfaces through which preauthentication is allowed are
configured.

Add a new param "rsn_preauth=0/1" to the configuration that enables
or disables preauthentication on the according bridge interface.

Preauthentication for unbridged networks is not considered in this
patch.
