Bug in Instance::getClone() generating unplaced copies.

* Bug: In Hurricane, in Instance::getClone(), the Instance::create()
    was called with a wrong number of parameters, causing the the
    wrong overload to be called. The position was thus not copied
    generating an unplaced copy. This was causing error in the
    AM2901/datapath bench, because fixed blocks where becoming
    unfixed.
* Bug: In <bootstrap>, in coriolisEnv (again) an error in the
    detection of the LD_LIBRARY_PATH.
