wpa_supplicant: bump to version 2.2

Patches are now upstream.

Enable epoll support since any modern kernel/toolchain supports it.

Interworking requires Hotspot functionality which we didn't enable
before so introduce a new option for them.

While at it group and sort the options in a more lean and friendly way.
