[B.A.T.M.A.N.] [PATCH 9/9] batctl: Allow to read list of interfaces as normal user

[Sven Eckelmann <sven@narfation.org>]

The list of interfaces attached to a batman-adv interface can be read by a
normal user via rtnetlink or sysfs. Only modifying this list requires more
acesss. Don't artificially restrict access to this information by the
batctl sucommand.
