All WPA APs were getting set as WPA2 due to the check for privacy; WPA/WPA2 APs *must* set the Privacy bit according to the standard, so we'd never end up in the case for NMAccessPointSecurity.WPA. Fix that, and also add flags for WPA[2] Enterprise which we'll use a bit later for the first-time connect case for 802.1x enabled access points.
