treewide: use wpad-basic-wolfssl as default

In order to support SAE/WPA3-Personal in default images. Replace almost
all occurencies of wpad-basic and wpad-mini with wpad-basic-wolfssl for
consistency. Keep out ar71xx from the list as it won't be in the next
release and would only make backports harder.

Build-tested (build-bot settings):
ath79: generic, ramips: mt7620/mt76x8/rt305x, lantiq: xrx200/xway,
sunxi: a53
