nl80211: Use the new bridge port option proxyarp_wifi

The initial IEEE 802.11 ProxyARP functionality in the kernel needed
changes in behavior and that ended up requiring an independent
configuration parameter to be used. Update hostapd to use that new
proxyarp_wifi parameter instead of the earlier proxyarp.
