hostapd: wpas: add missing config symbols

This adds missing config symbols for interworking as well as Hotspot 2.0
to the wpa_supplicant-full configuration.

These symbols were added to the hostapd-full configuration prior to this
commit. Without adding them to the wpa_supplicant configuration,
building of wpad-full fails.

Thanks to Rene for reaching out on IRC.
