hostapd: Add wowlan_triggers config param

New kernels in wiphy_suspend() will call cfg80211_leave_all() that will
eventually end up in cfg80211_stop_ap() unless wowlan_triggers were set.
For now, use the parameters from the station mode as-is. It may be
desirable to extend (or constraint) this in the future for specific AP
mode needs.
