hostapd: fix conflicts hell

Add each variant to the matching PROVIDERS variables after evaluating
the respective hostapd*, wpad* and wpa* variant.

Each package providing the same feature will automatically conflict with
all prior packages providing the same feature.

This way we can handle the conflicts automatically without introducing
recursive dependencies.
