Fix for radvd startup on OpenWrt

We are adding a ugly hack for OpenWrt based Piratebox. The clean
solution is to add another extendRoot package (extendRoot-radvd), but
after 1.1 the major OpenWrt release will change and this new package is
obsolete.
We only add this ugly hack, which will be removed on development tree
later again.
