Since vfc_ci has been merged wih the main verificarlo repository and is
now available in Verificarlo's Docker, the source code of vfc_ci can
now be removed.
Also, vfc_test_h5.cpp has been modified so that every algorithm is
called directly. This results in a much shorter vfc_tests_config.json
since we don't need to vall vfc_test_h5 with all algorithms as
arguments.
