commit c3a4cddaaf ("hostapd: remove hostapd-hs20 variant")
as well as
commit 9f1927173a ("hostapd: wpas: add missing config symbols")
indicate hostapd-full should support Hotspot 2.0 already, but only
wpa_supplicant (and wpad) do.
How this happened is not really clear, as no commit adding support for
Hotspot 2.0 is in the history.
Fix this and add Hotspot 2.0 capability to hostapd-full.
