Take CORAL and COOL from original git repos and not install from prepacked *master* tarball

The is follow up on Charles Deloit's obervation on discrepancy on CORAL and COOL builds from HEAD of its repos. It turned out that we use very very old procedure for CORAL and COOL installation from master. Using a dedicated jenkins job we create a tarball from master and then install it from LCGCmake using master as version. As version of tarball (master) is not changing we don't reinstall CORAL and COOL with new commits. Now CORAL and COOL are handled in the same way as ROOT, cloning it directly from original repos.
