mac80211: fix some dependencies and make lib80211 compile without cfg80211 selected

* libertas: does not depend on mac80211 but on cfg80211 and it uses wext
* libipw: also uses wext
* net-hermes: it is enough if the main package net-hermes depends on cfg80211
* Now it is possible to build it without cfg80211 at all
