Use jinja2 templates in statistics test

- Merge ns*/statistics-channels.conf.in config snippets into
  conditionally rendered section in ns*/named.conf.j2 files.
- Turn ns2/named.conf.in into ns2/named1.conf.j2 because it is used
  later in the test to restore the original config.
- Symlink the ns2/named.conf.j2 ns2/named1.conf.j2 to pick a starting
  config.
