radvd: Add init scripts and sample configurations to documentation.

- The init script, radvd.init, is directly from the debian package.
- The radvd.conf.empty is from the redhat specs dir in the 1.0
  sources - added here rather then using it from the package because
  it wasn't present in the 0.7.2 and I want to avoid breaking that
  version.
