ethernet: T6709: move EAPoL support to common framework

Instead of having EAPoL (Extensible Authentication Protocol over Local Area
Network) support only available for ethernet interfaces, move this to common
ground at vyos.ifconfig.interface making it available for all sorts of
interfaces by simply including the XML portion

  #include <include/interface/eapol.xml.i>
