hostapd: Fix AP ctrl events not send to hostapd_cli

Android hostapd aidl calls wpa_msg_register_cb() to register
onAsyncWpaEventCb to monitor ctrl events, this overwrites ctrl
iface's callback hostapd_ctrl_iface_msg_cb.

This results hostapd_cli not able to receive AP ctrl events from
hostapd.

This CL defines wpa_msg_register_aidl_cb() for Android hostapd
aidl to make sure both aidl and ctrl iface callbacks are triggered.
