Updated the build scripts for atlasexternals and Gaudi, to:

  - Make sure that the builds are properly re-configured, by explicitly
    removing the CMakeCache.txt file from the build directories;
  - Cleaning the build directory completely whenever the build of Gaudi
    is re-configured. To provide a temporary fix for GAUDI-1315.
