nl/cfg80211: advertise OBSS scan requirement

wpa_supplicant will do OBSS scan for drivers that implement auth/assoc API. Drivers that implement nl80211 connect API (rather than auth/assoc) may need wpa_supplicant to do this as well. Add a new feature flag to inform it (wpa_s) that a driver needs wpa_supplicant to do OBSS scans.
