Update Vc and fix the problems loading some libraries

Somehow (at least on some systems) the link order was such that the first directory was $SIMPATH/lib. This was even the case when the order was defined differently in the CMakeLists.txt. The problem isn't yet understood completely.

This results in the problem that libVc.a was taken from $SIMPATH/lib were it is installed by ROOT/FairSoft. As long as the version provided with CbmRoot and the version provided by ROOT were the same the problem wasn't seen. When updating our internal Vc version this results in a creash when loading libryries due to a version mismatch between the library version and the header file version.
