- Fixed KIWISatSolver to work with new solvables
  Unfortunately I was told that the current solver bindings provided
  with the perl-satsolver package will no longer be maintained. Instead
  there will be a new lib and package called libsolv. kiwi needs to
  adapt to the bindings for libsolv in order to stay compatible with
  the solver results of the zypper package manager. At the moment the
  problem of the new "self-conflict" feature could be solved by
  setting set_allow_self_conflicts in the old satsolver library,
  which is what this patch does. For the future we need to support
  libsolv though
