radvd: add /etc/radvd.conf

When starting radvd without any configuration the following errors would
be triggered.

"""
root@intel-x86-64:~# systemctl status radvd
● radvd.service - Router advertisement daemon for IPv6
Loaded: loaded (/lib/systemd/system/radvd.service; enabled; vendor preset:

"""

Normally the user should create and configrue the /etc/radvd.conf
manually.  However the radvd provide a example file for redhad located
at "radvd/redhat/radvd.conf.empty". When installing, it would copy
radvd/redhat/radvd.conf.empty to /etc/radvd.conf. Also add this empty
conf here to used as an example of configuration
