Title: Feature: Check Presence of Traces of Legacy CernVM-FS 2.0.x

This checks for typical traces of the CernVM-FS 2.0.x server tools and refuses to do anything in `cvmfs_server` until they are removed. Furthermore it defines any **cvmfs-server** package older than 2.1.x as a conflict in both RPM and Deb packages.
