package/wpa_supplicant: Fix options to actually disable features.

Since wpa_supplicant 2.8, most features are now enabled by default,
instead of being disabled by default. Remove setting of options that are
already enabled by default, and turn ENABLE into DISABLE where
appropriate.

This also makes the existing options disable more features, otherwise,
it would still include dead code or even fail to compile.

Als correct/update some help texts.
