gnulib-tool: restore the ability to create a big testdir

[Bruno Haible]

Earlier it was possible to do
  $ gnulib-tool --create-testdir --dir=/tmp/testdir `gnulib-tool --list`
but this is no longer possible, since the config-h breaks a few other modules.

        * gnulib-tool (func_usage): Make module names after --create-testdir
        optional.
        (func_create_testdir): If no module was specified, use nearly all
        modules.
